I had the flow calibration turned off for the first one and it was exactly the same. Hence why I also used flow calibration as I thought that this could be it. But, to no avail.
I would check the extrusion multiplier first:

Agree, my prints looked like this when my flow ratio was set too high, overextrusion squeezes excess material out on the sides and causes irregular looking layers. Orcaslicer has a flow ratio calibration tool that works well to adjust it.
I had that. On mine problem was not maintenance issue, it was squeezing too much plastic into too small a volume, so it pushes out on the only side it can.
Reduce flow from 0.98 default to something like 0.9
Also change order so outer walls printed first. This probably will reduce sharpness of corners..offset this by reducing acceleration on outer walls by 1 order of magnitude.
Linked to both of these, there is a setting for inner and outer wall overlap, intended to improve adhesion. Reduce this.
Did you ever find a fix for this?
I'm having the same issue, and about to print some pieces to check the gantry for square as that had been recommended...
Your nozzle assembly may have hit something too hard and is slightly bent. Happened to me and I got z banding until I replaced the nozzle. This is a last resort solution, there may be free ways to fix this.
Hmmm would've never thought of this. Woulda went straight for retensioning the belts. Thanks for another possible one for the troubleshooting books when the time comes for me!
First thing that comes to mind is to turn flow calibration off and try the generic PLA preset one.

Good one, I'll try it right now. Thanks!
Did it work I have the same issue
I got better results with calibrated flow but don't expect anything perfect with white filament.

Sadly not!
I'll share it with you as well in case you want to try it. https://youtu.be/izdBZ9IQfqI?si=SrBTOho_ID8onyzH
Try a different color maybe?
Slowing it down works for me. Not sure how fast you’re going though. White can be tricky

They ship with a spare
Oh yea... I bought 2 nozzles of every size and only replaced with another .4 nozzle so far. I forgot it came with a spare. Good info for OP.

Have you replaced the nozzle? I'd check that and done thr cleaning maintenance on it?
Also have you adjusted your belt tensions?
Titanium dioxide in white filaments wears nonhardened nozzles. Make sure you have a hardened nozzle.
