OneNote Windows 10 doesn't open

I've recently been receiving this error message.

After 2 days, OneNote W10 refused to open. Every time I click on the app, the starting screen flashes and closes. The app doesn't appear in the Task Manager. 

Things I've tried: 

Restarting PC

Deleting settings.dat

Deleting cache

Repairing the app

Resetting the app

Uninstall/Install the app from Microsoft Store

Uninstall/Install Office 365 (both 32 bit and 64 bit)

I'm running 64 bit Windows 10 if that helps. 

If anyone has had experience with this, please let me know. 

Thank you!
