Rhino File Freezing on "Creating Mesh"

Hi, apologies if this isnt posted in the correct forum, but Ive been running into a recurring issue which has bricked my project file for school and Im not sure where else to seek help.

After I attempted to split/trim a complete surface Rhino froze. Now when I open up the autosave it gets hung up on “creating mesh” when I try to move out of wireframe mode. There are other people in my class who have run into the same problem and nobody can figure out whats going on.

Hi - please start by running the Rhino SystemInfo command and copy-paste the result here.
Apart from that, could you post a file that is behaving like this on your system?
