Hi! I had workable blender long time ago when I used it (in summer). Now, it crashes every time I click 'Video Editing' from menu.
Terminal says this:

$ blender
Color management: using fallback mode for management
Color management: Error could not find role data role.
Read prefs: /home/bob/.config/blender/2.83/config/userpref.blend
Color management: scene view "Filmic" not found, setting default "Standard".

Deletion of config gives nothing. Would you please recommend something to do?
