The version via pip that I used above is very old (0.0.2).

I installed the master version via pip install git+https://github.com/new2f7/streamdeck-ui (PySide2 dependency disabled). Now the UI launches and it seems to work. There is only one warning when launching: libEGL warning: DRI2: failed to authenticate

@new2f7 Can you verify which version of streamdeck-ui you have installed? The call stack suggests it’s not the latest version (1.1.3). I’m not saying it will fix it, but start there.

WRT troubleshooting. The error KeyError: None basically means it could not find the stream deck serial number in the deck[] dictionary. The initialization fo that dictionary is done earlier in the code but not knowing which version you have installed makes it difficult to make progress.
