[2023] I can't climb anymore with my Controller

Hello, I am playing AC Valhalla with an EasySMX PS3 Controller. After just 30 minutes of playing, i am not able to climb anymore. Walls, buildings, mountains, i can't climb anything of it. The strange thing is: i can still climb, when I use my keyboard. But i really would like to play with my controller. The first minutes of playing, the climbing even worked. It stopped working after about 30 minutes, when I visited the first village (forgot the name) where I have to rescue my crew. Anyone has an idea? Thank you very much.
