My computer hangs when I "share screens". How do I start diagnosing it?

I've just updated to the latest version (22.04.1 LTS) of Linux through the official updater and my computer is very unstable when sharing screens. I've been having this issue in OBS, Chrome and Discord. When I share screens, everything works fine for anywhere between 30mins and a few hours before the system will ultimately hang (no stop code or screen; the GUI just freezes in time and goes unresponsive; mouse doesn't move). The only way to recover is to either force reboot it (hold the power button) or [REISUB](https://unix.stackexchange.com/a/33891/539122) What are my next steps to fix or figure out what went on? Some unrelated information but may be useful: * OBS is using "Pipewire" * My system complains of an ACPI BIOS Error AE_ALREADY_EXISTS
