Bug The character sticks to the wall when jumping, and I can move along it in the air.

I have a character from the asset store, and when I jump and look slightly towards the wall with the camera and press the W key or any other key for movement, there is a bug condition where the camera is facing the wall. Then, after jumping in the air, I can hang on the wall without touching the ground, walk on the wall, and I don't even fall, even though I thought it should be like in real life. I mean, if you jump into a wall, you shouldn't just stick to it and start floating in the air, right? I couldn't come up with a solution for this. I wanted to make it so that when the player jumps or simply gets close to the wall, it doesn't stick to the wall, even if they are looking at it with the camera and pressing keys like forward or backward, etc. The same applies to jumping. If the player jumps, they should just collide with the wall, stop, and fall down. If they hit the wall at an angle, their speed should decrease, and they should also fall down. How can this be fixed? I can provide the code for character movement and the code for jumping (the jump code is separate). Here are some screenshots where I'm stuck in the air, and at that moment, I'm holding down the W key to do this. I don't want it to be like this; please help me fix it!

Thank you so much!!!!!! You are the best person in the world!!! I've been struggling with this for a couple of days and couldn't figure out how to solve it, and I even asked neural networks, but it didn't help. This was my last option, asking on the forum, and if it hadn't worked, I don't know what I would have done. Thank you again, I am very grateful to you!!!
