Question Forza Horizon 4 crashing - System Error 36871 ?

Nov 29, 2021
Hi All,

I'm hoping to get some troubleshooting advice. This game used to work fine but it's started crashing during gameplay after I picked it back up after 3-6months of not playing.

In Event Viewer I get a Event ID 1000 for the Forza Horizon 4 application, and under system I get a few Schannel 36871 errors.

I've tried running the game in Windowed mode, using suggest graphics settings, resetting the Xbox app, resetting MS game services, updating Windows, updating the game, updating Gfx drivers, uninstalling the game and reinstalling, reinstalling Windows 10 but maintaining files/programs via the MS tool and have run sfc /scannow in command prompt which repaired some corrupt files.

I feel like the Schannel 36871 error is the key but this is beyond my knowledge and hoping someone could explain what it is or how it could be linked.

Windows 10 21H2 19044.1348
I5 4690K
Asus Z97M+Plus
16gb Kingston DDR3 HyperX Fury Black

Bios settings are set to default

Thank you!
