Why all of a sudden does Fusion think MeshMixer doesn't support OpenGL 1.1

I have been fighting with a corrupt file (Thanks Fusion) and in my trying to get it to work I must have done something that made Fusion 360 think that my machine doesn't support OpenGL 1.1. After I finally went back to an older (prior to corruption) file I decided to save a file as STL which I always send to MeshMixer to do that. It has been working without fail since I replaced this machine 8 months ago. Now every time I try to send a body to MeshMixer I get the attached popup stating this system does not support OpenGL 1.1.

The only thing I can think of that might have affected this is, at one point, I tried choosing all 3 of the choices under Graphics Driver in Fusion 360 preferences. It is now back at the default of Auto-Select.

I have tried everything I could think of, completely uninstalling Fusion 360 and MeshMixer (Multiple times now), Updated to the latest NVidia drivers (Ryzen 7 & GTX 760), deleting all of the Autodesk folders under AppData Roaming and Local. Looked in the registry but didn't see anything I thought relevant. MeshMixer opens on it's own and I can edit an STL just fine but it will not open from Fusion 360 (now).

I've read of this issue (Google) but most times it is a new driver or something simple like that or the thread just ends without a resolution. Can anyone help me so I can start using MeshMixer from Fusion again. Thanks

Try MM 3.3 instead.

Or follow this to try a different version of opengl: https://forums.autodesk.com/t5/meshmixer/how-to-fix-meshmixer-not-opening-windows-10/td-p/9701918

Thanks! 3.3 worked.....odd that it broke all of a sudden. Software (crap) Magic!
