Yesterday I installed the x86_64 Ubuntu 22.10 to a brand new, clean drive. After it finished, I added Visual Studio Code, htop, mc and copied some source code and projects into my home directory.
This morning, I was warned that support for 22.10 would be ending soon and urged to upgrade to 23.04, so I did. (Using the GUI upgrade interface.)
After the upgrade finished and the system rebooted, everything seems to work great -- EXCEPT for "files" (nautilus?) Any time I try to open that I see a message that "files has stopped responding" and an offer to close it or wait. Waiting doesn't help because the same message reappears shortly after clicking wait.
I'm not an expert on linux and even less on a linux graphical desktop, so I have no idea what to do.
FWIW, I was able to get Visual Studio Code working, as well as Visual Slickedit (a 32 bit program!) and they don't seem to have a problem letting me browse for files to open. That's probably not related, but I'm primarily a Windows programmer and almost all file open/save dialogs are actually part of the Windows File Explorer, so I thought that maybe nautilus provides that service as well. Sorry if I'm stupid, just thinking out loud.
