hmm, ok, that's clear. What I can say right now, is that we have quite close HW
configuration - with the only 1 exception - your laptop has buit-in 4K monitor,
in our case we have regular fullHD monitor AND - external 4K. All other things
look the same 8-/

About - what to do next, I see 3 more things to try...
1. Could you please try to make an apitrace of the hang?
Tricky thing here - chrome should be run in a single-stream, manual higher
should help.
>From here you can take apitrace https://github.com/apitrace/apitrace/
Who knows, maybe with apitrace we also will reproduce it, or somebody other
will try too.

2. Did you try on other distributions? For example ubuntu or manjaro (doesn't
matter actually, just - another distro)

3. I am recalling 1 issue, where we had quite similar case - reporter had
stable hang, and we couldn't reproduce it on our side. And then he updated bios
version, and it helped https://bugs.freedesktop.org/show_bug.cgi?id=107586
I don't say that we have exactly the same case, but - I would check and bios
version also (just in case).
