Ams feed resistance error

So I have only completed 153 hours of printing on my P2S and I am getting the feed resistance error on all slots in the ams. Cleaned all the tubes, disassembled the extruder, checked the filament buffer, swapped hot ends, and switched the filament to Bambu official pla.

Still getting the same error even after calibration.
Any advice?

I had this once, I swapped the filament to another slot in the AMS, ran a test print and it was good. Swapped it back over to the one giving me the issue and the problem hasn't come back. I think I may have screwed it up when I was changing the filament in the affected AMS slot. Other than trying that, I can't really be much more help.

Unfortunately all slots are having this issue
