Does your app call SDL_GL_SetAttribute()? I’m guessing this is the error you would get if you request an attribute which that specific device cannot deliver.
Ah, thank you so much!
I had these lines and removing them fixed the problem:
SDL_GL_SetAttribute( SDL_GL_CONTEXT_MAJOR_VERSION, 3 );
SDL_GL_SetAttribute( SDL_GL_CONTEXT_MINOR_VERSION, 0 );
