Extremely high gantry twist

Hello, I'm trying to calibrate my V-core 4 500 after updating from hybrid to IDEX. During the beacon ratos calibrate i get this:
Gantry twist relative to the center


Extremely high gantry twist: 3052.809880μm.
You have significant scan/contact inconsistency which is indicative of mechanical problems, please investigate before resorting to software compensation.

What should I check? Before the IDEX assambly I didn't have any problem during the comission. I'll attach the height map and the message i got. My 3D printer is enclosed, I tried removing the upper door just in case the umbilical was causing any trouble but I didn't have any kind of improvement.

Any ideas about how to improve this? Thank you.
