I’ve had something like this happen on my prusa. A bug maybe. Sliceing for 0.6mm but some somewhere somehow either in firmware or slicer it got set wong so it only extruded as 0.4 and it looked just like this. Opdated firmware and slicer profile and it worked fine again. But yeah it looks proportion wise like wrong nozzle size about the difference between 0.6 and 0.4.
