mmap() error Operation not permitted - Wine/Proton, Aliens: Fireteam Elite


Hello!
I am having some trouble with Aliens: Fireteam Elite from steam (Proton). It crashes on startup with whatever Proton version I try (regardless of steam version or 3rd party ex. glorius eggroll github).

So I launched the game with debug to get a log:
Code:
WINEDEBUG="+timestamp,+pid,+tid,+seh,+debugstr,+module" %command%
There are 8233 occurences of this in the log:
Code:
err:virtual:try_map_free_area mmap() error Operation not permitted
But I don't feel comfortable disabling this kernel security feature (CONFIG_STRICT_DEVMEM).

It feels like I'm missing something, do all the other distros really have this kernel option disabled? *UPDATE* I checked on Ubuntu 20.04.2 LTS" and this kernel security feature is on.

It's rated Platinum at ProtonDB so It should work.

Wait, I'm getting the same thing on other Proton games like Foxhole that worked before.

I got past this mmap by creating "/etc/sysctl.d/mmap_restriction_override.conf "

Code:
vm.mmap_min_addr = 65536
*UPDATE* I'm marking this as solved for now since my problem is something else.

Path of Exile (which is the first protondb title which isnt native... sort of) works with glorius eggroll proton, so proton works for me with other games at least. Foxhole worked before though so something is b0rked *tm since my last upgrade.
