Crazy bouncing issue

[Light Grenade]

Hi all, 

I'm encountering a really bizzare bouncing issue. Upon export (fast bounce, or slow bounce) my waveform peaks at the very beginning and the rest of the file looks like white noise. After I have exported, the session goes a bit haywire, and pressing any button results in clicking, crackling, and general horribleness. I had a listen to the file outside of the daw, and this happens. I can only get the session back to normal upon re-starting. It's a heavy session, but everything plays fine. I have frozen every track to lighten the CPU load, and haven't installed any new plugins recently. 

As you can see from the video, I am experiencing what seems like some sort of interference noise when moving any control on my interface when the file is opened. This only happens when I open the dodgy file, all other bounces are totally fine. This also happens with bounce to track inside the session. 

Any help would be appreciated.

Do you have 64 bit mixing enabled?  If so, try turning it off: I had one plugin that behaved like this years ago.

I totally forgot to say, but this solved my issue and made my life way easier. 

I disabled 64 bit exporting and it exported as normal. The error seems to only occur on heavy sessions. Before this I was re-routing my entire project so I could record into an aux track.

Thanks!

Likely a specific plugin not playing nice with 64-bit double precision then the net 'weight ' of the project.
