Same error on Windows 10 Pro

Previous version Flipper 0.190 works fine for me (Windows 10 Pro)

This issue has been persistent since v0.193.0.
I have a feeling the development team behind this library DO NOT actually build and test before releasing.

The last version that worked for me on Windows 11 was v.0.192.0

Is the server mode is on?
If yes, I resolved this issue by installing old version of Flipper in other dir, run it and disabled this option. After I run a fresh version of Flipper as expected.

Your advice works for me. Thanks!

But I'd like to work with "Server mode = ON"

Same for me with version v0.229.0. I've checked what is this pid and it was Flipper itself. After restarting the application I see another screen Failed to start Flipper. Error: FlipperServerConfig has not been set and there's no information how to proceed from this point

Exactly same issue here, tried to restart the system but error persists

That's a different issue and has already bin fixed on the next release. Just upgrade your Flipper.
