[2019] Fallout 76 crash on startup. HELP

Yesterday (and basically today, i was playing till 2:00 AM) Fallout 76 worked perfectly, no crashes, no bugs, no problemsa at all.

Now, every time i try to start it it gives me a black screen for 2 seconds, a "1" on the FPS counter appears, then it goes back to desktop, closing itself.

I tried everything, changing the Prefs.ini, updating the Nvidia drivers, changing OneDrive properties, running as Admin, Scan and Repair. Nothing worked, still crashing on desktop.

I did everything i could do, except reinstall. But since it took 2 days to install i seriously don't want to do it.

UPDATE: Shows error 2.19.740.16.10.2583

UPDATE 2: Error was for trying to run it as an Admin. Still crashes on startup, tho.
