Can you provide a log after trying?
From the top menu:
View -> Developer -> Open Current Logfile

What do you mean with "last error not set" in the issue title? Where is that shown?

"Last error not set" is the error message on the smartphone (first device) when the connection process on the Win11-system fails.

Are there any private issues in the log file? I saved it as .txt, could post it here or send it as PM.

Are there any private issues in the log file?

might be better send it as PM. for example to [email protected] or to me in the forum on https://support.delta.chat/u/simon/summary

Also that "no error" is displayed is an android bug, so I'll move this issue to the android repo now.
(could maybe be solved by using jsonrpc for this function? just an idea, I don't know how the code works in android)

iOS has same problem of being unable to show real error message. This is basically a case where the trick of get last error that we use when using the cffi is not working in this case, maybe a missing error event in core? anyways I think simple solution would be to use jsonrpc, because there methods return errors directly.
