Firefox and Chromium do not open any longer. I fixed firefox by re-installing the snap. But re-installing chromium-browser did not help.

The error points to permission issues. What is the correct permission for the files and how could they have changed?

/snap/chromium/2011/snap/command-chain/desktop-launch: line 52: /home/username/.config/user-dirs.dirs: Permission denied
sed: can't read /home/username/.config/user-dirs.dirs: Permission denied
/snap/chromium/2011/snap/command-chain/desktop-launch: line 261: /home/username/.config/user-dirs.dirs: Permission denied
cp: cannot open '/home/username/.config/user-dirs.locale' for reading: Permission denied
/snap/chromium/2011/snap/command-chain/desktop-launch: line 266: /home/username/.config/user-dirs.locale: Permission denied

This fixed it; purge was essential

sudo snap remove --purge chromium
