I have seen with my P1S a recurring issue with the filament not going through the sensor blob on the back of the printer cleanly. I would call it the AMS hub, but I only have the single version on my printer. It appears that the filament feed through the PTFE and gets blocked at the first connector there. This causes the failure you’re seeing. I would check the PTFE tube there and make sure that it is smooth and fully inserted into the printer.
GITD filament is much rougher and abrasive. Thus I believe that it is not recommended for use in the AMS. I use matte quite a bit and up until this problem started, had no issues it with.
