SOLVED An unexpected error occurred when upgrading to version 1.5.16

Help Desktop App
1

When prompted, I upgrade from 1.5.15 to version 1.5.16. When I start my computer this morning, I get the error message “An unexpected error occurred”. I can manually unlock the vaults.

I use Windows restore to fall back to the earlier version (1.5.15). The Cryptomator app disappears.

I install the old version of Cryptomator 1.5.15 and get the same error message for each vault, “An unexpected error occurred”. Now I cannot open the vaults manually.

I install version 1.5.16 again. I still get the error messages, but I can open the vaults manually.

Windows 10, 19042.867
Cryptomator 1.5.16 .2831

Thank you @infeo, that did the trick.

On a side note, I made a “clean” install of 1.5.16 on an older pc, and it worked like a charm.
