Every time I have a Teams call in Windows 10, using my Parallels 16 VM using the FaceTime camera from my iMac, the call is OK for a few minutes, then freezes a couple of times for 10 seconds a time, then after a few minutes the VM crashes completely making it unusable for a few minutes, and then the iMac restarts. I then have to reset the VM to get it to restart as the resume fails once it has re-booted. This is starting to make Parallels un-usable for me, as I spend most of my day on Teams and in Teams calls now. I have MacOS 10.15.6, and Parallels Version 16.0.1 (48919). I have tried disabling TRIM, as others have mentioned for similar issues. and it makes no difference.
