One blueprint slows entire engine whenever opened

I have one blueprint called “EnemyShip” that gradually slows the entire engine until I have to close it using task manger. I thought it was corrupted so I replaced the BP using a version of it from the backup folder but the issue still happened. I then got an even older backup of the project where the issue wasn’t happening and replaced the current BP with that one and the issue is still happening. The issue has happened on multiple computers and all other BP’s that I have tested have not had this issue. I have run out of things to try and was hoping that anyone has seen this issue before and knows what it is.

I just wanted to clarify, the slow down happens whenever the BP is opened in the editor.
