Pro Tools constantly crashing while saving

[1176LN]

Hello!

I have been having this problem for a long time but now it became completely unbearable.

Pro Tools is constantly crashing while trying to save the session. I disabled auto-save so I could have at least a couple of minutes of peace.

Crashing occurs randomly. Sometimes I can save 3-4 times, then it crashes. Sometimes it crashes about 10 times in a row even if I open the session and try to save it immediately (in both cases, with Cmd+S and "Save as...").

Crashes occur while using either digital or analog onboard output.

What has already been done:
- Memory check by Apple Hardware test (as some members mentioned "KERN_INVALID_ADDRESS" as a possible memory issue) - no problems found
- Reimporting session info into a new session
- Trying to copy the project to the internal SSD
- Changing on how many cores should PT run
- Making sure owners are ignored for the external drive
- Trashing preferences, DAE folder, volumes, plist, databases etc.
- Turn off Bluetooth and Wi-Fi

Here's an average crash report:
