Why does my character get intermittent delays in rotation while moving my character forward?

I’m having a strange issue with blueprint programming. I’m quite new at this, and it seems like a basic issue, but I can’t seem to find any answers in other questions.

Currently, I am working on a top-down scenario, without starter content. I managed to make my character move forward when I hold W, and turn to the right when I press D. Both functions work fine apart from each other, but when I run forward and turn at the same time, the character is experiencing strange delays in the turning sequence.

I assume the issue is something simple, like using the wrong method for rotation or something. If anyone can find the problem for this, thank you a lot!
