Games using proton_tkg_9.21.r1.g32abf9fc get stuck on 'launching' in steam

[StelardActek]

I've been building proton-tkg myself in order to test out NTsync. I was able to build a working version of 9.20, however when I try the same process now the proton-tkg.sh script builds 9.21 and that version gets stuck at the 'Launching' stage in Steam. As best I can tell, the game itself doesn't actually start at all.

After waiting a few minutes to check, I would run pgrep -a wine to see what is running, and I would get something like the below:

1533368 /home/stelardactek/.local/share/Steam/compatibilitytools.d/proton_tkg_9.21.r1.g32abf9fc/files/bin/wine64 start.exe /b C:\Program Files (x86)\Steam\Steam.exe /home/stelardacte
k/.local/share/Steam/legacycompat/iscriptevaluator.exe legacycompat\evaluatorscript_2139460.vdf
1533406 C:\windows\system32\wineboot.exe --init
1533411 C:\windows\system32\winedevice.exe
1533421 C:\windows\system32\winedevice.exe

Out of curiosity I ran the command /home/stelardactek/.local/share/Steam/compatibilitytools.d/proton_tkg_9.21.r1.g32abf9fc/files/bin/wine64 start.exe /b "C:\Program Files (x86)\Steam\Steam.exe /home/stelardactek/.local/share/Steam/legacycompat/iscriptevaluator.exe" legacycompat\evaluatorscript_2139460.vdf and got the following output:

Running the same command against 9.20 gets a similar output except without these lines:

003c:err:service:process_send_command receiving command result timed out
003c:fixme:service:scmdatabase_autostart_services Auto-start service L"winebus" failed to start: 1053

And the command actually returns to the command prompt with a ShellExecuteEx failed: Path not found., I presume because I'm not in the correct directory for the relative path legacycompat\evaluatorscript_2139460.vdf

Hopefully this is all relevant and useful information. Sorry if it isn't.
