Fatal Error on NSR then crashes Steam on my side?

[Shaymin]

Last update: Okay I think I'm done debugging the situation. I restarted my computer, verified the game's integrity. I redid the Audition Tutorial on my own THEN letting P2 join the Remote Play Together. Once we got to DJ Sub fight, the remote play crashed on P2, resulting in me crashing my whole Steam + Game. Sure I could use Parsec but that's extra steps and more headaches.

Hi, I'm not sure what I'm supposed to do with this error: https://imgur.com/QwD0Lte
Notes:
I'm (trying to) play with Xbox One Controller, bluetooth.
Player Two is playing with keyboard using Remote Play Together.

Steps on crash:
- Start Game
- Invite P2 in Remote Play Together
- Enable P2 to have keyboard/mouse control
- Start Game
- After a minute or so, popup occurs. Steam crashes and restarts. (I even had one time where it said Steam was UPDATING)

And this happened three times...

EDIT: Live updating this issue...
- Launching game already leads to Steam already crashing:

- I do see a new version for my GTX 1070 on GeForce Experience, I'm updating as of right now...

Will update on this

EDIT AFTER UPDATING GPU DRIVER
- Okay was able to play the game just fine....Until I alt+tab away to look on discord and the same Fatal Error occurred and crashed Steam. Cannot win...
- Also I'm playing windowed mode since I have ultrawide monitor and I want to stream it on Discord VC. Not sure if necessary to bring up.

I had the same issue a couple of hours ago, when I quit the game, I got that error message.

Hey Shaymin, so sorry for not attending to this earlier. After the patch v1.1.2, do you still face the same error when you Alt-tab away?
