Game Porting Toolkit: Any .exe exits immediately with no output

Hi Apple & devs,

I'm trying to test various Windows .exe files using the Game Porting Toolkit (GPTK), but I’m hitting a wall: no matter what .exe I try, the command returns instantly with no output — no error, no logs, nothing.

Here's what I'm doing:

I'm using macOS Sequioa 15.5 on M1 macbook pro.

I installed gameportingtoolkt GPTK 2.1 through brew from gcenx:

brew install gcenx/wine/game-porting-toolkit

When I run any .exe using GPTK's wine64, like this, e.g. with steam

user@JMacBook-Pro / % WINEPREFIX=~/wine_prefix /usr/local/bin/gameportingtoolkit 'C:\SteamSetup.exe' --verbose
user@JMacBook-Pro / %

Immediate exit without any return code, output, nor errors.

No output, no crash, no logs. Same result with simple test apps

Running with WINEDEBUG=+all (still no output)

Even running wine64 does the same thing.

I’ve tried:

Removing and reinstalling GPTK

Creating a fresh WINEPREFIX

Checking /tmp and ~/Library/Logs for logs — nothing

Has anyone else experienced this or have any idea how to debug it? Is there ANY Apple support for this??

Thanks in advance.

Why is there absolutely no support for/by Apple for the Game Porting Toolkit?
