CTRL + SHIFT + T doesn't work anymore, I tried it on Windows and Ubuntu. The other shortcuts work fine.

CTRL + SHIFT + T doesn't work anymore, I tried it on Windows and Ubuntu. If I go to history > recently closed tabs and click on something, it works, it's just the keyboard shortcut that broke. The other tabs keys work fine.

Create a new profile as a test to see if your profile is the source of the problems.

See basic troubleshooting: make a new profile:

There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins" in case there are still problems.

If this new profile works then you can transfer files from the old profile to the new profile (be careful not to copy corrupted files)
