Filament loading and unloading in monochrome printing

I’ve been printing one thing for days
in a row, one set every day, today the printer went crazy, halfway through the print it started pulling out the filament in the AMS and pushing it in and repeatedly… and it reports an error of course… can you help me ? the pictures are today’s but I’ve printed everything about 3 times and no problems…I don’t see a problem in the print itself… I’m flashing the slot in AMS red. I will send a photo if necessary. I’m printing monochrome and halfway through printing it started going crazy…it’s writing an error on the PC: 0700 8006

Thank you all for your advice and help
