Halo Infinite freezing the whole system

Nobody has claimed this yet.

I've always had occasional freezing with Halo Infinite but I've noticed it a lot more lately.

To describe the freezing, it locks up my entire system (Alt + F4 has no effect, etc). I can still hear the game running but everything else seems to not run (like Discord calls not hearing anyone and they can't hear me). I can get my system running again by doing a [`REIS`](https://github.com/MadLittleMods/linux-notes/issues/44) (part of a full REISUB) but the `I` is necessary to forcibly kill all running programs otherwise Halo Infinite is still stuck on my screen.

```sh
$ pamac search mesa --installed
[...]
lib32-mesa 1:24.2.8-1 multilib
Open-source OpenGL drivers - 32-bit
mesa 1:24.2.8-1 extra
Open-source OpenGL drivers

$ glxinfo | grep Mesa
client glx vendor string: Mesa Project and SGI
OpenGL core profile version string: 4.6 (Core Profile) Mesa 24.2.8-arch1.1
OpenGL version string: 4.6 (Compatibility Profile) Mesa 24.2.8-arch1.1

Previous Halo Infinite problems were the game not launching at all: https://github.com/MadLittleMods/linux-notes/issues/32

Relevant issue in the Proton tracker: https://github.com/ValveSoftware/Proton/issues/5030

Start by reviewing the listed Manjaro, kernel, Mesa, GPU, Halo Infinite, and Proton versions, then compare the symptoms with Proton issue #5030 and the earlier issue #32. Reproduce the full-system freeze if possible; done means documenting a confirmed cause or a reliable workaround.
