Doesn't work on Xiaomi Mi 9t (MIUI Global 12.0.3) and Windows 10 (2004)

Well. It's working now! Thanks.
Replacing the adb files and removing the -g did the trick

Does adb devices show your device?

https://github.com/Genymobile/scrcpy/blob/master/FAQ.md#device-not-detected

[AlexTCGPro]

I just ran adb.exe through cmd with the commant get-state. No device is found

[rom1v]

That's the problem then. Try to install the drivers (see previous link).

[AlexTCGPro]

Well, tried to update drivers from multiple sources, including oem.
Sadly, the problem persist.

No device is ever found.

[rom1v]

Check on stackoverflow how to make your specific device detected by adb.

[AlexTCGPro]

I have an update.
I just tried the Vysor app, which too mirrors the phone in a very similar way.

It does detect the phone, asks for debugging permission and can install its app from the computer.
Doesn't seem to be a driver problem after all. It must be something with adb as you say

[AlexTCGPro]

Replaced sndcpy adb files with theirs. They were different.
It succesfully detects the phone.
But brings out this error:

What is the result of adb --version?

java.lang.SecurityException: You need the android.permission.INSTALL_GRANT_RUNTIME_PERMISSIONS permission to use the PackageManager.INSTALL_GRANT_RUNTIME_PERMISSIONS flag

See #39

Just downloaded adb files directly from google servers, they appear to be the same as the Vysor app.

Android Debug Bridge version 1.0.41
Version 30.0.4-6686687

In my case, the same error appeared.
I tried to run the .bat file in the same directory as my apk in debug mode, but the following error appeared:
INSTALL_CANCELED_BY_USER
So I enabled these options on my device, in developer options:
Install Via USB
USB debugging (Security settings)

I didn't run the .bat file again I just ran
npx react-native run-android with the device plugged in, and then it worked.
