Rhino 6 Viewport Error/ crashing issues

I am not sure what is happening with my rhino files. It first started crashing when I was changing materials/ exporting viewports. It would repeatedly crash. Then, it started to crash the files immediately upon startup. It would load for a while, and then crash. I was saving files as I moved along, and I could usually move back to an earlier file which would open. But it still crashed with those too. After trying a bunch of things, I updated rhino, and my graphics drivers, and now the files will open, but the viewports are either black, or showing a static view.
I am very confused, and don’t know what to do at this point.


Things have gotten really messy with my files, but here is one of the files. And a screenshot of the viewports now.

I updated my graphics driver, and also uninstalled and reinstalled rhino. It seems to work now (at least one of the files - that wasn’t working previously).

For any further ideas and suggestions please reply with the result of the Rhino command _SystemInfo.

My files are still being very odd. The only file I was able to open was a backup version of an older save. The file that was working for me yesterday won’t open again. Like most of my other files, it just loads for a bit, then crashes.
Here is the system info:
