Crashes while updating

[langp11]

• Description: Update game...(wait for downloading, testing file...) Crash with this message

• Traceback:

  File "cddagl\ui\views\main.py", line 3764, in step

Error appears while the status bar is counting files in my saves directory - it got to over 300,000 but I didn't see the final figure (file manager suggests 358,388) so not sure if that bit of process had finished or not.

That main.py file doesn't seem to exist (presumably packaged inside something else) so I can't do any further investigations.

Possibly related: I have also had a 'something went wrong' message trying to backup my saves. There isn't an identifiable error message, just a rapidly flashing window that has to be killed in task manager. I switched OFF 'backup saves before updating' before getting this new error so it isn't the same thing, but it might be the same cause. Or not.

Later: Possibly because my save directory is large (>4GB)?

The 'previous_version' directory appear to have the new version.
