Character Controller's step offset is glitching

i am currently working on a project where I use the character controller paired with another script to controller my 3d character. while I was playing I noticed an issue with the character controller where it would "rubberband" (jitter around) while I was trying to move over an obstacle that was too tall to jump over. i have gone around and tried to find a way to fix this and I also did some debugging however so far i have not found a solution.
