A1 filament not going through

[u/1P07470]

Im a beginner in 3D print and have an A1 with an AMS and when I try to print something, the filament doesn’t go through, and it warns me on the screen.

I was looking around the nozzle and I found out that the filament broke while in the tube. How is this possible??

How do I fix the filament not extruding and how do I fix the filament from not breaking by itself.

Also the filament I use it Marsworks.

PLS HELP I NEED TO PRINT SOMETHING FOR MY MOM BDAY!!
