Problème stl 3D model import

Hello, shapr 3D no longer wants to import my 3D model in stl format. The first time it worked. But now it’s still lagging and it doesn’t work. Sometimes shapr 3D tells me that my file is damaged. Can you help me?

I reduced my stl file to 33.2 mb. it does not work either
