Thank you! This was what resolved the issue for me. I had the exact same problem both with Watch Dogs: Legion and Valhalla. Games would just exit to desktop without any error message after 20 minutes of playing. I had the same thing in the logs. Turns out Denuvo does not like it when your clock is not precise. Mine was 5 minutes behind and after I manually adjusted it the problems went away. Playing for 6 hours now without any issues.Originally Posted by fantazyz78 Go to original post
I've been trying for the past week to fix the problem of crashing at around 20 minutes of gameplay, I've just tried this fix of syncing the clock and my clock was indeed a few minutes off.
I've been playing watchdogs legion for about an hour now without any crashes and I will now test if assassins creed is able to run stable.
TLDR syncing windows clock looks like it was able to fix my crashing
