I can't read the wall thickness in the posted image, but that might not be a concern. I see the layer thickness is 0.28 mm, which is very close to the maximum for a 0.4 mm nozzle. Have you tried a smaller layer thickness? Using a layer thickness of 0.2 mm is pretty common.

Consider also to try a different slicer. PrusaSlicer is quite capable, may have a profile for your printer, is free and easy to use and may shed some light on the problem.
