Interestingly, it just halted at the same command:
selectWindow, TAB=Open command
But it didn’t “stop” or produce an error in the log tab. The little green line-number was still visible on the icon in Chrome.
Yesterday I had faster, fibre internet installed - that’s the only thing that’s different ← just in case that may be a factor.
Just throwing it out there, don’t know if this helps to debug it. Apologies if this is just clutter.
