Need help with weird a shadow baked on static mesh

It’s a mesh I have exported to UE5 from blender, shadows have spikes along sharp corners.
The mesh has a ridiculous amount of triangles because I wanted to see if it would be fixed, and I am also using 4096 ShadowMap Resolution (Yes, I know it is overkill.) it’s just to see if would help.

Does dose anyone know how to fix this?
