Can anybody inspect my file please?

I'm trying to subtract cylinder out of another parts

but somehow sketchup says my part is not solid. I welded all lines properly.

part was made by shape bender and I need to cut circular shape using subtract.

please check my file anybody

The Cylinder is a good solid.
The other complex-form has several tiny issues.
Misaligned edges and faces that are a tiny bit out of coplanar etc.

However, you can still achieve what you want, before fixing those more awkward problems...
Simply edit the cylinder and intersect with model, then edit the complex-form and repeat the intersection - reverse the parts of the cylinder to be correctly oriented...
Delete the unwanted parts in the two groups, then recombine those two sets of geometry into one...

See the illustration...

I used SolidSolver to fix the result [without deleting coplanar edges]...
See the attached SKP...

need solid inspection.skp

thanx for your time, TIG! problem solved.
I think.......... shape bender sometimes make some unexpected transform slightly, doesn't it??
