ZorinOS 18: Session Crashes After Unlocking Screen from Automatic Lock

After upgrading from Zorin OS 17.2 Pro to Zorin OS 18 Pro, the wayland session occasionally crashes when unlocking the screen after it has been automatically locked due to inactivity. The session ends abruptly, forcing a full re-login and restart of all applications. This issue does not occur when manually locking the screen.

Steps to Reproduce:

  1. Upgrade from Zorin OS 17.2 Pro to Zorin OS 18 Pro.
  2. Allow the screen to lock automatically due to inactivity.
  3. Attempt to unlock the screen by entering the password.
  4. Observe that the session crashes and returns to the login screen.

Expected Behavior: The screen should unlock successfully and return to the active session without crashing.

Actual Behavior: The session ends unexpectedly after entering the password, requiring a full re-login and restart of all applications.

Frequency:

  • Occurs intermittently, but only when the screen locks automatically due to inactivity.
  • Does not seem to occur when manually locking the screen.

Additional Notes:

  • The issue started immediately after upgrading to Zorin OS 18 Pro.
  • No error messages or logs are visible at the time of the crash.

What can I do to find a solution?

The session just crashed while I was playing a game.

Does this happen in Xorg, too?

Switching to Xorg at login...

Restart your computer, at login screen, click your name. A cog :gear: wheel appears, click the wheel, then click "Zorin OS On Xorg."


Same issue here, on wayland. If I suspend the session then come back, everything is closed. If I just lock my pc and wait like an hour and come back, I have to log in twice again and everything is closed.
Edit - Yes it's also intermittent for me, either suspend or just locked. After getting past the first sign-in the screen will go black, and then I'll have to sign in twice and the desktop is fresh.
