Devolutions Server Update Wizard doesn't finish up

Hello,

I updated my Devolutions Server to the most recent version today. Did the same with my locally installed Remote Desktop Server Manager.

Now i have the following problem: The Wizard won't finish with the green "success" line i am used to, i just get this:

When testing functionality i can use the Devolutions Server via Web but i cant login anymore from my locally installed RDP Manager. I get this error, also i added the Log Export as Attachment to this post.

Has anyone a clue what went wrong here?
