I've been having an issue similar to this on 22.04 (jammy) and don't recall experiencing it on 21.10. It's actually happened not just from standby but from just being on (with display off) as well. I'm still testing, but it could be extensions like 'blur my shell' causing an issue. Couldn't find anything associated with this in /var/crash or in errors.ubuntu.com for my id.

I can't move the mouse or type anything. After a while, it unfreezes. This is quite annoying because often the freeze is long enough to send the screen to standby again for absence of singal, so then I have to wake it up and wait again. This is not 100% reproducible but happens very frequently, both when the screen is locked and when it's not.
