Hi evidence,

If there is a problem, please save it with assets. Then please use Dropbox, Google, Adobe Apple, or Wetransfer as cloud service, with no zip, no tiny URL, or hidden URLs.

Images typically do not tell me much. I can see that the mesh has very few points, which can also be misleading in an image.

The file would need only the main shape that you like to cover. If that is below 1MB, then it should load here as c4D

All the best
