Save stops working in After Effects 18.2.1 on macOS 11.4

I have a repeating and critical issue, when save just stops woring in After Effects 18.2.1 on macOS 11.4:

- When I hit Cmd+S, it doesn't save (I still see an asterisk of unsaved file in the application bar, and file modified date is not changed since last save).

- When I use Save, Increment and Save, Save As, Sava a Copy... menu actions — they do nothing.

The same happens to some other functions related to file system, like Import — I see Import menu action active, but clicking it also does nothing, just as double clicking in the Project pane doesn't open import dialog.

I just lost 30 minutes of work because I use Cmd+S intensively and couldn't even think that it does nothing: when I quit the application it prompted me to save my project, I clicked Save, and then reopened the app to see in the starting screen that my file was last saved 37 minutes ago.

Very disappointing. For app not saving your work — it's a critical or blocker issue. Please investigate.

I still have this problem appearing: After Effects suddenly and with no visible signs stops executing any menu commands. I still can do editing in compositions, but nothing else works. The most critical part of it is that 'Save' stops working too, and depending on how far into editing I notice that, it always means loosing some work time.

Is there any Adobe representative here? Where can I report it?
