Anki crashes before opening

Hi. Anki was working fine yesterday.

When I tried opening it today, it shuts down automatically before even syncing.

Already restarted my pc and uninstalled and installed newer versions to no avail.

If someone could help me, thanks in advance.

*Tried to downgrade version 2.1.35, but it says to downgrade my deck?

Did you follow all the steps on When problems occur - Frequently Asked Questions, including trying the 2.1.50 and disabling add-ons?
