CS cart issue during import 4.13

I have been stuck on this issue for a while, now. Initially, this was a theme issue and it got solved. But now, it seems to occur within the products. There are some third-party packages used to import data but this one seems very recurring.

I don’t know why it occurs. I’ve tried reimporting, and testing imports with well-mapped fields and categories. I haven’t tried clearing and adding them again, but I think I’ll save that for last.

This is the issue when I go to the individual products.

Is it an image issue? It might be, but with reimporting, the same issue occurs. It should be updated, right?

Also, after importing any data, the products list page displays the above error and doesn’t function properly.

Hi!
