VFAs on Core One+ vs Mk4s
Unfortunately having the same issues and the more I print on the Core One, the more I regret the upgrade from my well printing MK4S to the Core One. Don’t have anything else than the Prusa belt tuner. But obviously all the things you’ve tried ain’t made a difference at all.

Prusa Core One + Upgrade kit Selftest calibration failed
By "core XY origin calibration", do you mean the "homing calibration" that clunks around in the front-right corner of the printer? If so, it kinda sounds like you already did some troubleshooting. Definitely make sure your gantry is perfectly square and your belt tensions are in the recommended rang
