Degenrate Triangle warning

Hello,

I was working fine on my project until yesterday, the editor starts lagging whenever I navigate near to some objects and I get a warning messages about degenerate triangles. I tired to fix the geometry in 3ds max and it seems that the meshs doesn’t have any geometry issues but some overlapping vertecies which I corrected but still having the same issue. the editor view prot become responsive only when I remove those objects from the scene. how to fix this ? is it a bug in UE5.02 ?
