Cannot run program "/home/[omitted]/Games/forged_alliance/downlords-faf-client-1.5.0/lib/faf-uid": error=2, No such file or directory

This shows when I try to run faf on linux.
Ubuntu 20.04 LTS
Current Linux Steam
Proton 4.11

It occurs to me that faf-uid is located in /natives/faf-uid and not /lib/faf-uid, although I don't know how to fix it, and I'm assuming it's compiled in somewhere.
Same configuration runs 1.4.6 just fine. There's no spaces in the username.

Here's the full error:

There should be a .vmoptions file in your downlord's client install you need to add -DnativeDir=natives
