So what had happened was that I was trying to get an AppImage application to run that required fuse2. I installed libfuse2 (I think it also prompted me to autoremove some things) and now I can’t get the system to boot.
It gets as far as asking me to enter the password to decrypt the drive and then after a second, I see the following:
Have you tried switching ttys (Ctl-Alt-F1 etc)? The last 4 messages in your pic hint at GPU problems. It’s possible that the system is up and running but the DE hasn’t started.
If no one comes along with a solution to the underlying issue (I’m afraid I don’t have one) you could boot a live distro and use that to copy the important stuff somewhere safe.
