Tried starting with gpu disabled, same issue. Running signal-desktop 8.20.0-1 from extra.

Tried renaming the config folder in .config/Signal and restarting. It came up and required me to scan a QR code to sync with my phone. When I scanned the QR code, the phone said the QR code was invalid.

My error. I was scanning in the wrong place. Once I scanned in Link New Device, it worked. Not sure why the config got corrupted in the first place, if that was even the problem, but I removed the old config after renaming it.
