System wide freeze with Nvidia GPU

If I launch a game with prime-run. then alt+tab out of it for longer than a minute (if I need to find help online for example) and then back to the game, the whole system freezes. Sometimes this even happens right in the middle of a game.

The mouse cursor moves but I can't close the game or open the task manager, I can't kill Xorg with CTRL+ALT+BS, and I can't switch to another virtual console. I can't use magic sysrq shortcuts because my laptop has no sysrq key, and they don't work on a USB keyboard either. I don't think it's a kernel panic, because the caps lock LED doesn't blink.

At first I thought this was an issue with PCIe runtime power management, but this happens even with runtime PM disabled.

Laptop: HP Pavilion Gaming Laptop 17-cd1013na

OS: Arch Linux x86_64
Kernel: linux-tt 5.19.4-1 (same issue on linux and linux-zen)
Desktop environment: KDE Plasma 5.25.4-1
