game_shader_generic_garrysmod.dylib error

I saw a thread about this here, but I didn’t want to necro it, so here’s a brand new thread.

I am getting the error “game_shader_generic_garrysmod.dylib is either not designed to run on Windows or it contain an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.”, followed by the same message with “.so” whenever I try to launch SRCDS. Was this ever resolved? I tried deleting the problem files and re-updating to no avail, and also tried wiping out the server and doing everything from absolute scratch, which still failed.

Any help on this matter would be much appreciated!
