Hello there, I am really sorry to said that the game may not be able to provide support on devices using arm64 architecture, due to the current configuration of the game.
However i will still try to seek for method to solve it, if possible.
Viewing post in Will support for 64 bit android systems be added?
I don't want to sound smart, but I think it's enough to change the application building configuration to IL2CPP: https://docs.unity3d.com/Manual/IL2CPP.html
Of course i don't exactly know how you made your game I just wanted to give some tips or whatever.
