How to repeat:
Installed Workbench .22
Setup tcp/ip connection thru ssh
try to connect ... promts for password login to ssh.
click ok ... crash

Suggested fix:
???
Tried reinstall of both workbench and MS visual C++ 2015-2019 without any luck.

Hello Jonatan Matthias Vinterbaek,

Thank you for the bug report.
I'm not seeing this issue at my end on Win10 with workbench 8.0.22.

Ashwini Patil

Same problem version 8.0.27

Hello, we are seeing the same issue. 

We recently pulled an old machine into our Domain without reinstalling Windows (Windows 10 Pro). With a Domain-User we get the same error, when switching back to a local user everything works fine. Tested in 8.0.27 and 8.0.22. 

Anonymized log: see Attachment

Any help is appreciated.

Quick update:

I was able to resolve the error. As seen in the log files, our user had a "ü" in his name, which - for some unknown reason - resulted in nothing working. When changing the "ü" to an "ue" it works again.
I don't know if this is a general problem with special chars, but worth a try I guess..
