Please help! Battlenet not launching

Hello everyone. I wrote this message in the steam deck sub Reddit but I had no answers. I want to share what is my problem with battlenet and now if someone had the same issue and how they solved it. So, I just installed battlenet and then diablo IV, and after closing it and tried to launch it again the app did not work. I changed versions of proton and it did not work. Does anyone know how to fix this issue. Thanks!
