Unfortunately, I haven't been able to test the beta yet because my notebook is broken and will be repaired.
Try out Enpass beta
The only difference I found is the program icon.

I've solved the problem, at least a workaround for the problem.
Download the Traditional Win32 from the Enpass website. The error does not occur here.
I hope it helps you until the problem has been resolved by Enpass.
Same for me. I have already completely deleted the program.
I also deleted the data from Enpass in OneDrive. Then I reinstalled the app.
Restored my vault from a backup. And then I reactivated the synchronization. Didn't help either.
