Hello Jim..
Yeah, true..

It's a gigabyte i9 9900k on Windows 10 with 64g ram..

I'm running pro tools 2021.12..which seems reasonably solid so far apart from this..

I've gotten a couple of access violations errors before some of the crashes.
I have disabled the windows microphone as I was getting an error notification in Biab at times..

I'm getting to generate maybe twice before it crashes..either with the access violation error or just a "pro tools has stopped working and will quit" error before the crash..
