Got an error message after i try to run a xamarin code on my Xiaomi mi 9

Question

I enabled the developer function on my phone, enabled trubleshooting, checked with powershell that my device is detectable on my PC.
(Also corrected every non english letter l used before like ó to o and é to e).
Everything seems to be great at this point, but after i want to create a xamarin program and run it on my phone i will get this error message every time:

What should i do?

Answer 1

For me this was the solution:

In MIUI the UI does some of the optimization for some reason, but this comes out to be an error while running the app on the phone through Android Studio. We need to stop the optimization:

Go to -> Settings -> Switch on the developer option (hope you know) -> Go to developer settings -> Turn off MIUI optimization
