I accidentally dropped the red pill. And took 17 blue pills…
Have you tried the online version of Office? 365 I think. I haven’t tried it myself, but I’ve heard that it works well.
As far as Onedrive goes, there’s a client that can be set up for real time syncing, like the Windows client. It’s also called onedrive, and it’s available here:

There’s a GUI extension by bpozdena that’s very good too, and it’s linked from the github page 👍
EDIT: Sorry, after I posted I saw where you said you’ve tried the online version of Office >.<
If everything else seems to still be running, it might be the graphics card driver that’s crashed. When it happens, hold down the windows key, ctrl, and shift, then press B. That should restart the driver and hopefully let you see if anything else is happening.
If restarting the driver works, it’s worth trying a different version before swapping hardware.
Good luck 👍
