Thanks for your answer.
I have Xiaomi mi 10 ultra and the last ROM 12.0.15 V12-10 stable worked fine. After update on 12.1.1 V12-11 has appeared clone apps problems. Now I see that it is android 11 issues.
But there's information from other users, that on China's original ROM 12.1.1 V12-11 stable cloned apps are working normally.
So that's why I asked for some solutions for xiaomi.eu ROM 12.1.1 V12-11 stable...?
