V3.1 Catastrophic failure - massive layer shifts

I'm starting to have layer shifts in my 3.1.

Config is:
- BRS z-upgrades
- x-axis Schleif-Tec upgrade
- self-sourced

It already printed for hours, then I stopped to wait for a new hotend, I changed the motherboard and switched to RatOS 2. I've printed a couple of little things (test cube, first layer test 350x350, benchy, etc) pretty consistently. Then when I print long and somewhat tall parts, I have some shifts. The more volumic the part is, the bigger the shift. You can see the ultimate print that shattered my ASA duct....

I've been checking the belt tension, moving the head manually everywhere to check for collision, nothing. It can print a benchy with speed, so I'm not sure what is problematic.

I've tried staying up close for the first layer, but it takes hours. I'm planning to install a camera and record constantly to see if that helps.
What would you suggest? Has anyone see this already?

Thank you!!
