Can't open Rhino Files after installing newest update

I updated as requested and now cannot open any of my files which were working perfectly prior to updating.

HI Joseph, Can you open Rhino and type SystemInfo into the command line and paste the results here?

What was the previous Rhino version you were on?

When you say can’t open files, is it only the ones you were working on? can you create a new file, save and reopen? If its a particular file please send or post the file. Rhino - Upload to Support
