"Unlock failed. See log file for details" /OneDrive

Hello! I get the following error message now suddenly when I try to open my vault (in my case a OneDrive)
I managed to find the log, but I lack the expertise to make sense of it, so I thought id reach out to you guys and humbly ask if someone with a kind soul and the know-how (or several) to help me.
I store incredibly much in there, and I wouldn´t hesitate to even reward a person if they are able to fix it, not to mention it would be incredibly generous.

Cheers, and thank you all in advance

Hi. I’m not sure if this is the solution, but I can see that you dokany version is outdated.
Here’s the latest version 1.3.1

Hi, I updated to the one you linked.
However now it opens but all my files are wiped :confused:

Can you provide another log file?
