I have dozens of effects on my tracks and busses but I tried bypassing them and ended up getting Audio Engine Dropout again. I thought it could be plugin related but I'm not using any plugin I haven't used in other projects before.
It does seem to be project related, because I opened an older project that has even more tracks and effects and no problem there... I guess I need to figure out what's different about this new project (there is a new VST I just started using but these problems predate it).
Regarding specs: i5-13600K, ASUS Z790-Plus, 32GB DDR5 RAM, 256GB SSD, GTX 2070 Super, Windows 10, DT 770 Pro, no audio interface
And nothing else is running except Chrome but with no audio or video.
HWInfo64 seems to show everything is ok (no disk issues) and Latency Monitor says my system appears to be suitable so far (not sure how long it's supposed to run).
