Hello,
Welcome to our Microsoft Q&A platform!
Hi, gagrim808-4020. Do you change the adb installed location? Please make sure the Android SDK can connect the emulators. To verify emulator connectivity, you could refer to this doc: https://learn.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/troubleshooting?pivots=windows#deployment-errors
You could also try restarting the adb server: Tools > Android > Restart Adb Server.
Best Regards,
Jarvan Zhang
