I am assuming you have boundary layer/inflation/prism layers on cylindrical wall. You will need to reduce surface mesh size. If you use coarser surface mesh size on cylindrical surfacw with so small inflation then it may give bad elements. So please refine surface mesh further.
The min orthogonal quality should be above 0.1 to proceed to solver. If it is less than 0.1 then please improve the mesh.
First check the locations of the bad elements. Please see following video for the same.
Once you have locations, please check if you can improve mesh using different mesh sizing. Please see following video.
You can see more information about sizing at following link.
