Latest Rhino build crashing on launch

Hi, I’m having a problem with my WIP Rhino.

I have the latest build, whatever that is and my os is up to date too.

Not sure whats causing it but last night I was working on a design, I tried to move some surfaces which caused it to crash and then every time I’ve tried to re-open it since it crashes before I can do anything.

Any one else having issues?

Is “it” a) Rhino new document - OR - b) the specific file?

If (a) - try reinstalling Rhino. Can you launch Rhino into a blank document?

If (b) - only the specific file, post/send the file to McNeel and post your system information to help the devs determine a cause.

If the file does not crash other systems such points back to your system.
