This was a great read. I wonder if the reason for the game client surprise crashing could be investigated the same way? Do the executable integrity checks run during runtime? What if one of those fails while it’s running, do you get a different disconnection message?
What surprise crashing are you referencing to? Crashes can be investigated in theory but Valve sends crash reports to their servers instead of storing them on disk. It's harder to analysis if you didn't catch a crash live with a debugger attached. And that is hard because of their Anti-Cheat (VAC) though not impossible (disable VAC).
I feel like this should be rewarded in the same way as the GTA V takes forever to load-writeup. https://nee.lv/2021/02/28/How-I-cut-GTA-Online-loading-times...
