Hello. I have been trying to make this model for a wile. When I run it through PrusaSlicer 2.9.1 it says there are extrusion errors. Is there a way to either adjust the model or the the slicing on the printing program? Thank you for your time and assistance.

The base is composed of faces that are mostly inverted normals, which will prevent the model from being sliced and printed. The inside of the cape (nearest the body) has scattered faces that are inverted normals as well. If you have Windows 10 or Windows 11, you could run the model through the repair feature of 3DBuilder (free) but the inverted normals may destroy the model entirely.To avoid the destruction of the base, I inverted the normals, quite easily, in meshmixer (free) and then imported it to 3DBuilder. The repair took quite a while, but the result, when loaded into Meshmixer, passed the Analysis/Inspector with zero errors and it appears the model is generally undamaged (and now attached).

If you are using Blender you will want to use the face orientation check. This will show you the direction of the normals for the model faces. Additionally you want to toggle on the 3d Print analysis add on that is built in to Blender but not automatically enabled. Go to Edit > Preferences > Extensions > check checkbox for the 3d Print add on. You can then check to see if your models are manifold. The original model has wrong facing normals and is also not manifold.
