Firmware 3.7.2 Selftest Error

This is the first update that somehow doesn't work on my MK3 Standard without MSU.

After the successful firmware update to 3.7.2-2363 with PrusaSlicer 2.0.0, the self-test breaks and even if I want to print something always with the error message : check X axis length...

In the self test you can see that the X axis does not move fully to the right.

But if I load the previous version 3.7.1 onto the MK3 again, everything works perfectly again!

I downloaded the 3.7.2 again and updated the printer. But the same error behavior.

Did someone have the same problem here?

do a factory reset with data clear and the you need to re-do the full calibration wizard

But with the 3.7.1 the  calibrationWizzard worked.

Manually check for friction on the X-Axis - powered off, the extruder should freely move left to right without any hesitation or stickiness. If the extruder "grabs" or "sticks" anywhere along the path, loosen the screws on the back of the extruder near the bearings. Then try again. If the friction goes away, then you can snug the screws back - but leave them less that tight. This is a known issue.
