FacebookActivity could not be started when I have an activity-alias

I have set the icon change dynamically in my app. Icon switching is set with an activity-alias (as described in the Android documentation). After changing the icon, and then changing the activity, login with Facebook no longer works with error "Log in attempt failed: FacebookActivity could not be started. Please make sure you added FacebookActivity to the AndroidManifest". My AndroidManifest.xml is configured as Facebook's documentation. Do you have any ideas? Thank you.
PS. The code I'm using right now is just a test project but partially replicating what's configured in my main project :)
Change Icon and Facebook login functions

How can I make this possible?

When using flutter run you should be able to hot reload pressing r and to hot restart using R. Just press them in the terminal where you've used flutter run.
If I remember correctly, launching flutter run you should get all these info on the console as a message when starting!

I had same issue on M1 MacBook with Flutter version v2.5.3 and I tried that way and it worked.
Open your project's android folder with Android Studio
Wait for Android Studio when it installs missing plugins and syncs Gradle.
Open your project on VSCode, debug and have fun!

Answered!
Finally I found solution - just reseted android stiudio settings to defaults and downloaded plugins. See screenshot attachedenter image description here.
