It says It could not find a suitable emulator

[Supreme Leader]

where did you read that it works with any emulator its clearly says works with memu only and android 5.1

Right here. I would use memu but I tryed both versions of it  (2.9.6 and 7) and both have google play store and services crashing every second, fully unusable for me. Couldn't even lunch the web browser or login because it would just crash right away... So I saw that it said bluestacks there and I wanted to give it a shot.... I don't think it will work at this point and I lost interest.

thanks will adjust that
and MEmu issues you're facing is duo to your system being problematic
