What could be causing this issue?
As far as I can tell, there's no debris under the plate. FWIW, printing a bunch of these.
RE:
Anything else I can provide? I've tried with multiple filaments, including the spool of Prusament that I got with the new printer. If it matters, this was a preassembled Core One.
I'm also using default slicer settings, not that any slicer would tell it to print like that...

Try running through X, Y and Z axis calibration and check the belt tension. Also, flip over the build plate and check there are no finger smudges or similar on the plate surface. If you are still running into issues it's best to attach your .3mf after zipping it so we can look at it. Also, contact Prusa support over chat.

RE: What could be causing this issue?
it looks almost like your front right side is lower than the rest of the plate... What happens if you drive with the manual controls the plate completely to the bottom? Weird noises at the end?
As hyger mentioned, a complete axes calibration would be my suggestion as well...

Or rather, when the Core One probed the bed with its nozzle and load cell, it falsely assumed the front right to be higher than it actually is.
Maybe the "crosstalk between heater current and load cell signal" problem is behind this and has caused an early, false signal when the front right position was probed? In the respective thread, the latest finding seems to be that pairwise twisting of the heater supply wires (in the main umbilical cord) can reduce or fix the crosstalk.
RE:
... or, read in another thread, the main cable sitting in the wrong place prevents the back side of the plate to fully reach the bottom position thus skewing all...

You mean the cable to the heatbed? That's the only one I could possibly see getting in the way of the Z movement -- and only if it was routed incorrectly upon installation, running in front of the rear leadscrew rather than behind it.
But even if that were the case, I would imagine that the automatic bed leveling can either compensate for the mechanical skew of the bed, or would show an error message if the deviation is too large to compensate?
RE: What could be causing this issue?
I am still wondering how that should happen but it was mentioned in another thread in the forum (I forgot which one otherwise I'd have put a link to it 😊 ) and I thought it would be worth mentioning this just in case. A rather macroscopic error but not everybody has gone through assembling a few printers themselves with the asssociated learning effects (a synonym for making silly mistakes) 😀

RE: What could be causing this issue?
This was a factory assembled printer. And support is sending me some replacement parts. Hopefully that fixes it.
