The problem with the APK on android

GODOT4 - v4.1.2.stable.ofical [399c9dc39]

=========

Hi everyone, this is my first time here. I have been using this program for about a year and now I made my first game, when exporting the game to Android, the game does not start, it gives the following error: ‘the application is not installed, because its package is invalid (for example, damaged)’. When exporting to Windows, there is no such problem and everything works well. What could be the problem?

Did you export the game without signing it? That happened to me too until I added the release signing.
