I cannot open the Rhino3d File saying "3dm is not rhino m archive file"

I’m using the Educational Version of Rhino 7. I save that file in my external drive - SSD.

I used “Rescue3dmfile” command and analyzed it, it says

"To find damaged parts of the file, search for the word “ERROR” in the following list.

====== FILENAME: D:\Thesis\모델링\Physical Model_2.3dm
ERROR Read3dmStartSection() failed"

Please help me out as soon as possible this is for my spring graduation exhibition project.

Thank you for your help guys
