I would just about bet Meshy AI gave a “non-manifold” model. 3-D models that are intended to be digital assets can have that issue, and I would suspect it’s easier for an AI to produce them versus properly manifold objects ready to be made solid.
There are ways to fix them though, and Meshy even has their own suggestions (Blender and Meshlab).
Definitely agree, it probably was a non-manifold mesh. There are several ways to fix this, but one of the easiest is to load it up in Blender, apply a voxel remesh modifier to it, and then re-export.
When I load a non manifold mesh into my slicer I get "error, click repair" a windows dll starts that repairs the mesh. It's weird that Windows does this instead of the slicer but I've never taken the time to investigate because I'm busy on the next print.
