Describe the bug
FGA crashes on Bluestacks 64-bit
Screenshots

The issue here seems to bit libhoudini (ARM to x86/64 translation) isn't working well with the app.
Proposed solution is to add x86 and x86_64 to the ndk > abiFilters section in gradle. I have tested and confirmed it's working.
Device Info (please fill at-least 'Device model'):
Added a simple PR to fix. Tested working on my Bluestacks
_I dont want to open a new issue post, because I dont think it's a problem that affects everyone. Probably just me.
So I'm going to post it here instead. I apologize for hijacking your post @thai-ng. I will post this comment as a separate issue if you find this comment troublesome.
I'm using Bluestacks 32-bit, build: v4.250.0.1070 Phone model OnePlus 5 (Android 10 I assume. Bluestack dont let you check)
When I was using the Canary build, and granted the .apk/app permission to overlay, it simply freezes when starting service.
It does not show a button for me.
Same problem occurs with older builds, as far back as April 2020. I dont know if it's a compatibility issue or not.
Lastly, I want to ask where is the Support Image Maker script / section in the latest Canary build?_

I had the same thing happen to me! I found a way to work around the issue though. In Settings, go to the Engine tab and set the Graphics engine to Compatibility. Once I did that, everything started working.
Image maker was moved to the very first option in the battle config list when you press play.

This is written in the Troubleshooting Guide, which every Issue template asks you to check first, under the Emulator section.
It's hard to spot that when I was tunneling visioning, trying to debloat bluestacks, while simultaneously trying to get the app working with a 24 hour limit left on the lottery.
Also, this was under the windows section. Adding a copy and paste text into the blue stacks will help people like me in the future.

The app works great btw. Really sophisticated, elegant and easy to use.
