Yes, I can do that. Same vanilla 1.21.8 installation, got rid of all the resource packs beforehand this time.

Yes, here it is. This is a vanilla installation, the packs it says do not exist are from when I played with mods.

I’ve been having this issue since 1.21.5. When I join a world, after about a minute (slightly different every time) the fps will drop to less than 0, and the window will stop responding between frames. Though in 1.21.6 and beyond I actually can’t even get to the main menu but that’s a different bug I am currently in the process of reporting
