Premiere Pro Crashes when pressing file button

Okay, so here is the problem:
Premier works fine, I can import, edit and play videos. I can even export videos. I can do everything, but whenever I edit or import anything in the timeline and click 'File' on the top bar, it freezes the entire software and crashes.

This also happens if I don't even try to edit or add anything to the sequence and press 'Edit' and 'Preferences'
This has made it difficult e for me to get my work done.  

I have tried:
Updating to the latest version of Premier Pro
Uninstalling and Reinstalling Premier Pro with reset preferences
Checking my Graphics Drivers and Windows 10 version is up to date.

The only temporary workaround I have worked out is pressing Ctrl_M and Ctrl_S for saving and exporting my work BUT I would prefer to not have this problem. it isn't great having the risk of falling to habit and losing work by pressing 'File' or having half the functions of Premier unusable because I can't access that particular menu. I can't even edit Premieres settings.
