Halo reach co-op wont go past maybe 5 minutes of gameplay with my friend

[fuzzystingray]

I am playing with my friend (i am PC he is steamdeck) and we load into halo reach and are able to run around for a bit in the story but at a random moment maybe 5 minutes in we get an error saying "the co-op has run into an error" or something and we all get booted out of the campaign. Is there any fix to this???? its happened like 5 times

you might have to boot the game with anti cheat off, as the steam deck version can only do anti cheat off.

weve done anti cheat off and the other experimental thing.

Having this problem among all of them. Hardwired into each other. Start a level, elim grunts, get about 3 minutes in, random boot. Been trying different fixes for about 12 hours now.

from the valve github on proton, the base for running windows games on linux/steamdeck: it seems that you manually have to install microsoft visual c++ redistributable 2019 on the linux machine /steamdeck. Your coop game should crash whenever you hit a checkpoint.

Edit: Try using flatpak to install protontricks. That should make installing the vcrun2019.exe easy.

Did this work? Running on Linux Mint and seem to be getting the same issue.
