This is a typical leveling problem for a beginner.
From the following pic, we can see that the nozzle scratch the bed plate. and cause the prints moves.

To solve this issue. Only need to adjust the knobs under the hotbed/ tighten it a little bit to give more place to the nozzle.
Here is a Youtube video guide for your reference.
