Hard to know what we are looking at with the pics except a thread problem.
Make sure the needle is inserted all the way up into the slot. It can drop down. Try a different thread to see if it shreds too.
Check inside the machine to see if a thread is caught in the thread guides. You have to take off the little screw caps and remove the screws to see inside.
Try a different size-type of needle to see if the results change.
What bobbin thread are you using for the project? Check the bobbin area and make sure it is clean.
Do you have the auto cutter? Check that area for stray threads too.
Hope you find the solution to the thread issues.
