Rhino file doesn't open stuck in "creating meshes"

Hi, I use Rhino 8, and one of my file doesn’t open and keep showing
“creating meshes” notification
this didn’t happened before and the only way to close the file is to force quit.

the file is about 450mb. Could anyone tell me what is the reason and how to fix this?
weird thing is that it only happen in the windows version and it opens just fine in my macbook

Hi -

I’d start a new file and make sure that all viewports are in Wireframe mode. Then Import the model.
-wim

oh that worked thanks!!!

Hi it worked after i imported in a new file but whenever i save and close and open it again, the same thing happens
is there any way to fix this completely?

Hi -

We’d need to see the file in order to be able to say anything more about this. Please use Rhino - Upload to Support to upload the file and make sure to mention this thread in the comments field.

Apart from that, how long are you waiting for the file to open? If I have to guess, you have some viewport in a technical display mode and, when opened, all the meshes need to be created. That can take some time depending on your system and your file. In that spirit, please run the Rhino SystemInfo command and copy-paste the result here.
