Can't understand how this is an Infinite Loop

Whenever I run my game, it throws an error saying that the following is an infinite loop, but I can’t seem to make head or tail of it. Can you guys help me out here? I’m still learning Unreal, and I was just trying to rotate my character by a certain angle over a certain period of time. I’d asked for help on this in a separate post but couldn’t get a solution, so I decided to try and make a workaround. Any help with either fixing the loop or suggesting how I can rotate a character by a certain angle over a certain period of time would be appreciated. Thanks.

For your reference, the initial values are:
Angle Rotated= 0;
Environment Rotation Angle= 180;
Rotation Amount per Iteration= 10;
