Hello, I'm working on M1 MacOS Monterey.
Next to having lost the ability to open MP4 files in PS and controlling my image export size via masks – I have discovered another issue:
Sometimes the usual PS hints/error messages and windows that require user answers (save before quitting?), will stop popping up visibly. They will block user interaction and need to be answered intuitively via shortkeys. Once the shortkey is pressed, an error messages will reveal itself shortly before closing.
The trigger for this is unknown to me. Restarting PS fixes it.
I'm not sure what is reported and what is not, so I'm just dropping it here.
