photoshop 2021: Please!! help me :( Pen Tool path curve guide error 어도비포토샵 펜툴 패스 곡선 시 이상한 가이드가 생겨요

Thanks for the reply. However, the pentool path color floats with a strange gradient instead of the existing blue. Also, a strange straight line guide is created when creating a curve as shown in the attached photo.

I installed a new adobe program but I’m still seeing the error. It’s my first time seeing this kind of error.. I’m not sure if there’s a problem with my computer.

When I click the icon you mentioned, the rubber band is turned off, but the path settings cannot be changed. I'll post a picture in the question post again, would you have a look at it? Thank you.
