Mesh Error

I get this error when meshing. I’ve been trying to make this project work for days and I feel like I’m getting further and further from ever finishing it. I used to be able to mesh this but then I couldn’t simulate it (there were errors w no actual messages). Now I can’t even mesh it. I tried moving the material point but it does not make any difference. Could anyone actually look at it and tell me how to fix it?

SimScale (second simulation, ducted rotating fan w boolean cut)
