Mac Steam Modules unable to compile

Hey,

I am having issues to get Steam running on Unreal Engine 5. The main issue is that the Steam Online SubSystem is not compiling for me.

I tried lots of different things now and nothing worked so far. When i add the SteamShared Module or SteamOnlineSubsystem as plugin to a blank project, I can regenerate the project files or recompile the solution.

I’ve been sitting on that issue for around 3 days now and no hope in sight so far, maybe you have a tip for me to solve that issue.

I am using UE 5.5.4 on Mac m3 Max (apple silicon cpu) with Rider as IDE.

This is what i use to regenerate the project Files:
sh “/Users/Shared/Epic Games/UE_5.5/Engine/Build/BatchFiles/Mac/GenerateProjectFiles.sh” -project=“/Users/blu/Documents/Unreal Projects/PhantomRacing/PhantomRacing.uproject” -game

This is the result:

fixed it by reinstalling the engine on mac. Might be some deeper issue.
