I uninstalled 5.4.1 because it was getting slower and when reinstalling it installed 5.4.4 and since then when i try to open a prejct it crashes on startup with this error message. I have searched the problem but nothing matches.

Edit: Tried opening another project and it also crashed, same error. I cant change versions because im in the middle of a shared project.
