RetroArch not launching games - LaunchBox 13.26, Windows 11

[Jasno]

Hello,

I'm running LaunchBox 13.26 on Windows 11 with an ACEMAGIC AM18 mini PC (AMD Ryzen 7, Radeon 780M integrated graphics).

I cannot get any games to launch through RetroArch. Here is what I know:

RetroArch works perfectly when launched directly or via command line

The correct command that works from command line is: retroarch.exe -L "cores\snes9x_libretro.dll" "FULL\PATH\TO\ROM\FILE"

ROMs are confirmed present at C:\Games\ROMs\Super Nintendo\ in .smc format

LaunchBox is installed at C:\Users\Jason\LaunchBox\

RetroArch is installed at C:\Users\Jason\LaunchBox\Emulators\RetroArch\

When launching from LaunchBox, nothing happens at all — no black screen, no error

The "Launch With" option is grayed out

Bulk editing games to assign RetroArch as emulator appears to work but games still won't launch

Games are imported under the platform name "Super Nintendo" but Associated Platforms only has "Super Nintendo Entertainment System"

Please advise on the correct configuration for this setup.

Thanks!
