What the hell Elegoo

I’m using a Neptune 4 plus and it said that there was a usb disconnected so it stopped printing. Once it stops printing it then kept extruding and became a big blob like the images above. This happened the first time with the one on the left, I thought it was my fault so I bought another compatible with the printer and hit print. This happened once again as you can see with the one on the right. What do I do because replacing it costed me $80 and j can’t keep doing this!
