Metaphor: ReFantazio crashes at startup under NotProton 1.1.0 with CrossOver 26.3, while the same game files and audio mod work through CrossOver. The failure is a read of 0x8FF at METAPHOR.exe+0x10ED299, immediately after reading the active fiber through GS:0x20.

CrossOver's launch wrapper initializes CX_APPLEGPTK_LIBD3DSHARED_PATH even when D3DMetal is not selected. NotProton calls Wine directly and omits this initialization. Set the path when the selected runner contains libd3dshared.dylib, and forward it through the open --env game-launch path. This restores CrossOver's initialization without a game-specific workaround or a new dependency.

Validation:

• Applying the same environment fix to the installed runner let Metaphor reach its title screen. The user confirmed working audio with the existing audio-fix mod; its log also recorded successful spatial-audio wrapper and stereo WASAPI initialization.
• The added envcheck cases fail before the fix and pass afterward. They check an absent library, helper inheritance, and forwarding a path containing spaces as one launcher argument.
• Passed make envcheck routecheck buildcheck settingscheck bridgecheck gamedrivecheck seedcheck.
• Passed make runcheck scriptcheck with ShellCheck 0.11.0, plus git diff --check.

Live verification used Apple Silicon macOS 27.0.1 and CrossOver 26.3.0.39832. A full application bundle was not rebuilt; the startup fix was verified in the installed compatibility runner.

Thank you again for finding the issue, identifying what the cause was (me being stupid) and fixing it :)

Thank you for this project! It's so nice to be able to launch Windows games directly from MacOs native Steam
