I have exactly the same issue. I updated from miui 12.0.2 (android 10) to miui 12.1.2 (android 11) an suddenly the controller is not working anymore on apps that were working before. Same mobile phone Xiaomi mi 10 lite 5G. Also tried some games recommended in razer kishi app with no luck. And tried to disable all the accessibility features of the phone with no luck either. Thinking on returning the product.
