Properties panel is blank Illustrator 29.3.1

Yesterday is was fine, but today out of nowhere my Properties panel is empty.
I tried to:
—Restart Illustrator
—Restart my computer
—Drag this panel left and than back
—Open Properties from the Discover panel
—Reset workspace preferences
—Delete Illustrator preferences and delete my OOBE files (following a long piece of advice that Bill Silbert usually gives)
—Delete Illustrator (with clicking REMOVE when it asks about what to do with preferences) and then installing it back
—Install Illustrator Beta just in case it works — and it has THE SAME mistake from the very beginnig!!
So nothing has worked for me so far. What should I do?
I really need help.
