Skin Width doesn't fix wall sticking,Skin Width doesn't fix the character controller to stick to walls

There are 3 properties in the Character Controller that can prevent from this to happend : Step Offset, Slope Limit, and Skin Width. However, I came to a point where I set all the values to extreme to make sure it won't get stuck. But the thing is that it still does. I have seen here https://answers.unity.com/questions/1477584/issue-with-character-controller-and-skin-width.html that someone like me realised that the skin width only applies to the front and the bottom of the character. You just have to press to the side to get stuck again. I have no clue of what to do, and I am just enough of getting things like these that shouldn't take that much time to fix. Thanks for any help.
