Hi i_rina,
Thanks for your response.
Yes, my MacBook Pro is crashing when running apps, unless I have the Zoom app also running. So strange!
When the MacBook crashes, the screen goes blank, stays blank for ~30 seconds and then shuts down, and stays shut down. When I turn it on again, the apps that were open when it crashed, open up again, and files are saved as recovered.
Apps do not individually quit unexpectedly.
The Mac does not restart unexpectedly.
There are no error messages.
My Mac is running the latest incremental macOS Big Sur update of 11.2.3, and all apps are up to date.
I started up in safe mode, and the same thing happened. I went to another user on my Mac and the same thing happened.
Thanks again for your response, any help would be much appreciated!
