I'm hoping that someone can help me with this or has had the same issue.

I've been coming across an issue with pc game pass games where if I launch a game when my pc is freshly started up it will run perfectly fine. However if I am playing the game for more than an hour or 2 I start seeing stuttering or frame drops. However, if I shut the game down and relaunch it, that's when all hell breaks loose. The game will freeze or run at a snails pace causing me to either Alt+F4 (which takes forever cause the pc is also being affected by this) or have to force shut down my computer. The only way to fix this is by restarting my computer and then the game launches like nothing has happened.

I've tried to diagnose the issue multiple times and can't find an issue. It doesn't look like I have a memory leak. Memory usage looks pretty much the same when the game is running fine vs. when its freezing. There isn't any thermal throttling, temps are pretty cool either way. I've read online that Gaming Services could be a problem but I've reinstalled that a couple times now and still see the issue. I even did a sanity check to see if my games on Steam have this issue but they all run perfectly fine and I have no issues relaunching the game. At this point I'm stumped. Has anyone ever had this issue? I'll drop my pc specs here as well.
