and noel...sorry for the less than hollywood cinematrography lol.

Either the way that works or doesn't work...CTRL A to select all in a linear fashion and make sure all the tracks are highlighted. I'm filmed through my phone. Will shoot you the Google Drive link.

Yes. Added the line to the ini and restarted. File/Export/Audio...still caused it to hang. If i do it through the Control Panel option, after the plug-in flush...within about 2-3 seconds I'll start to see the render tick forward. File/Export/Audio...after the plug-in flush...it just freezes and goes nowhere.

The above hang change tweak and no effect of the Control Panel Export option...that still worked as intended and the file exported correctly.

Added that and restarted and it didn't work. Seems like any Stereo Export originated from that dialogue window accessed via File/Export/Audio hangs right as it starts. The Export short cut on the Control Panel works. I mentioned the stereo comment above as late last night, I tried to export all tracks zero'd out as if I was getting them ready for another importing into another DAW from that same File/Export/Audio dialogue window...and that worked fine.

and though I normally wouldn't do it this way...I exported as an MP3 from the above method and that worked as well.

No actually...Advanced brings up the same Export dialogue window as File/Export/Audio where it chokes for me. The screenshot below method will work to fully complete the export with no issues. I've done it like 6 times with no issues.

Yes...seems to be. One completes correctly (the Export option on the Control Bar) while File/Export/Audio hangs every time for me. Thanks for your help thus far Noel!!!

Still rendered ok (only a quick listen) with both toggled on/off and that above Export method through the Control Bar. The only difference I saw was it moving right to the rendering stage with no flushing of the buffer,

You did...I did toggle that several times off/on yesterday. I didn't really see a difference. Also toggled off/on Plug-In Load Balancing and the system seems a little more stable with it engaged. Going to try this new shortcut method with both disengaged and I'll let you know if there's a difference.

So...it wasn't bound that to key...but went ahead and did that but it didn't work. Seems the only way I can reliably bounce down is through the below attached method. Anything to do with that File/Export/Audio dialog box keeps on choking as soon as it starts.

Spent all day yesterday and a bit this morning troubleshooting. First to comment about what appears to be an "inordinate" amount of plug-ins, on several of these projects the track count is at 170+. It's a very cinematic, orchestral sounding based pop album using tons of "real" instruments that were recorded peace meal due to budget/scheduling. So to create a full sounding string section, it's done track by track. Same thing with harmonizing on the vocals. I could submix but trackcount/playback is fine so I leave it. The way I see it, 136 plugins over a 170+ track count, I don't think is off the charts. Especially if CbB plays it back fine and renders fine...and was NEVER brought it it's knees on my i9 14900k. On to my observations and revelations on the current Sonar choking Export issue. Took 3 projects that play and render fine with CbB but have now been giving me problems within Sonar. To be clear, the play back is fine in Sonar but it chokes on rendering. Spent all day yesterday deleting FX bins, reshuffling/rebuilding FX chains to varying degrees of non-success. Late last night I tried "Freezing" all tracks and was able to render. Ok...maybe that's it? Maybe there WAS too many plug-ins within the project?!? Except this morning...I stumbled on something that I hadn't caught before, mainly because I haven't used this option that often and I think I "may" have found what the issue is? Whether there's a reason why or it's a bug that's not for me to say. USUALLY, I was going to File/Export/Audio in both CbB and Sonar (have ALWAYS done it that way)...choosing my options and file locations and hitting Export. It would flush the plug-ins and then choke. In Windows Explorer I could see that a file was generated but it would be stuck at 4kb. If I clicked on the screen...eventually it would go white and say that Sonar's unresponsive...do you want to wait or close. BUT...THIS MORNING...I DISCOVERED...that if use the Export Shortcut function on the control bar...ALL 3 PROJECTS RENDERED FINE. Listening to playback of the Renders from Sonar now and all 3 sound fine. So yes...a grateful workaround and maybe slightly less fearful about CbB going away...but that still doesn't make sense to me that one way of Exporting works...and the other chokes. Any thoughts as to why?

Both of those dump files were in the google link I sent you. I may have spoken too song about the culprit. More testing to come today.

I think that plug-in is part of the issue. Are there any pluses that might stabilize the situation by rebuilding the plug-in order? For testing, I had added an extra buss next to my main, moved all the plug-ins in the same order over the to the extra buss and bypassed them all. One-by-one...I rebuilt it by CTRL dragging the plug-in over to the main vocal, activating it...the exporting a small chunk. If that worked, I saved and moved on to the next one. Now...this test file I did it in seems more stable and I can get it to render or not render based on those two P821 MDN Tapes being either on or off. The other projects where I haven't rebuilt seem less repeatable hence my wonder.

Ok...through a ton of trial and error...it looks like it's PM's P821 MDN Tape plug-in. I have it running on all of my busses but for some reason, when it's on the vocal buss and the backing vox buss is when it stalls in Sonar. It does not do this in CbB. Would it have anything to do with how Sonar now has that Oversampling drop down menu in the plug-ins whereas CbB does not? That seems to be the only variable I can see...I've tried this on two different projects that had the same buss configuration/plug-in order. With that plug-in off in Sonar...they both render. With them on...they hang.
