Vertex count mismatch Problem importing Marvelous into blender

I followed the tutorial’s guidelines, everything seemed to be going well, but when I attempted to import and add the ‘Mesh Cache’ modifier as described in the video, I encountered the ‘mesh vertex count mismatch’ error. I’ve searched for solutions, but none have worked for me. Even importing the OBJ file doesn’t have the same menu as in previous versions of Blender, and the button indicated in the tutorial doesn’t appear as expected. Is there anyone experiencing the same issue or who has a solution? Please help.

Now, this menu doesn’t appear anymore, I’m not sure if that’s affecting the import process or not (Image below)
