I’m pretty new to blender so I honestly have no idea what’s going on here. I’ve attached pictures. One picture is outside the mesh and the other is inside the mesh. I would look it up but I don’t even know what to call this. I need help from the blender veterans please.
Looks like it’s probably intersecting geometry. Check to make sure you didn’t accidentally duplicate something.
If you’re unable to resolve the issue, sharing your file will make it easier for others to pinpoint the issue.
I dissolved the vertices near the slit and it closed the hole. The mesh still might be broken but the hole is gone.
