When launching the Slack desktop app it crashes out with "GPU process isn't usable. Goodbye.". It was running, but following this morning's update it now fails. I've been on holiday so the updates I did this morning bring in all the updates published last week. The full diagnostic output is:
ubuntu 21.10
kernel 5.13.16-xanmod1
slack-desktop 4.19.2

Initializing local storage instance
(electron) Sending uncompressed crash reports is deprecated and will be removed in a future version of Electron. Set { compress: true } to opt-in to the new behavior. Crash reports will be uploaded gzipped, which most crash reporting servers support.
