Does this happen across all speed modes ? have you tried calibrating to your filament

@F.Ahmed I have calibrated the filament, but haven't tried to experiment with speed modes. Thank you. Will try that.

All looks good, but for some reason, the outer walls are folded inwards a little bit. All walls are supposed to be straight. I printed it using Bambu Studio with default settings for Generic PLA.
What could cause such a defect and how to fix it?

Previously, I printed out a box that is a bit bigger with separative walls for minidiscs and it printed perfectly. In that model, other walls were thicker.
