Getting the same issues here, was working just fine over the weekend, loaded up the game this morning and I started getting this "Panic" error within 1-3 mintes of the game being lunched.
For troubleshooting I have:
1) Used both windowed and full screen mode
2) I have tried idling and staying in motion in game
3) I have tried just sitting on the login screen
4) Turning off effects
5) Completely uninstalled and reinstalled the game
6) Restarted my computer and exited out of any non-required applications (I.E: Discord, etc)
And this error still continues to happen.
