Weird Jump After Walking Into Wall and Releasing

Thanks for reading this. I've been working on a prototype for a metroidvania, and I got the basic walk, run, and jump down, but for some reason, after walking against a wall and releasing the walk button, the player springs into the air at a height around 1.5x the max jump height is set. I've tried to lock the y position when not jumping and not moving, but because of how I detect input, I can't find a way to make that work, so I tried to assign a physics material with a very small amount of friction, which does remove the jump bug, but then prevents my character from jumping when in a corner sometimes. At some point, I may use a physics material for a wall jump drag, so if possible, I would like to keep the friction 0 for as long as possible until I do this. Thanks for helping me out.

Edit: Quick update. I decided to use a physics material 2d, as well as a platform effector to prevent the player from sticking to walls. The original problem still persists.
