I'm having a similar problem. For reference I have a Galaxy S21 5G (Android). I have enough storage available.
I have the (Android) installation file installed, but when I press the file it opens a window with a loading bar saying "Staging app" for about 5minutes and then when the window appears with the "install" and "do not install" options. When pressing the "install" option, it just goes "app not installed". It was originally resulting in "package is invalid".
I hope this information helps the devs understand the problem?
