I eventually had to stop the snapd service and manually delete the "/run/snap*.lock" files and the "/snap/chromium" folder and the user "snap/chromium" folder (after backing up) then uninstall via apt with " --purge" switch and then snap remove with "--purge" switch too then restart the snapd service and then apt install chromium-browser. Launch and then close browser then copy user "snap/chromium" dir back from backup.
Test launch and all is back apart from my user profile name and picture but all bookmarks, form data, etc. are back. All is now working so you can close this bug if you want. Thanks. I still get the following if I launch from command line but it still works so probably not relevant: Gtk-Message: 19:12:04.332: Failed to load module "xapp-gtk3-module" Gtk-Message: 19:12:04.397: Failed to load module "canberra-gtk-module" Gtk-Message: 19:12:04.399: Failed to load module "canberra-gtk-module" WARNING: Kernel has no file descriptor comparison support: Operation not permitted [41845:42159:0427/191208.179138:ERROR:udev_watcher.cc(98)] Failed to begin udev enumeration. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1970611 Title: Chromium fails to start from snap after 22.04 upgrade Status in chromium-browser package in Ubuntu: Incomplete Bug description: Just went to open chromium to test a localhost website after upgrading to Ubuntu 22.04.

This means that running multiple instances would start multiple browser processes rather than opening a new window in the existing process. Aborting now to avoid profile corruption.
