This is most likely an error on your end rather than on Studio's. Please make sure you have the necessary permissions to connect to a usb serial port. For some linux distros, that's the uucp group, I don't know the details of EOS.

On windows 24h2, I have the same issue, I can use zmk studio online version, but local version can only discover the keyboard, can't connect.

Did you manage to make it work? I'm having the same issue on Fedora

Finally found a solution here: https://askubuntu.com/a/210230

Same thing with EndeavourOS Linux x86_64, solution was: sudo gpasswd --add $USER uucp
