Additional context How am I to stop the G service apps from crashing all the time? How should I install GMSCore?

I got MicroG to work by downgrading the Play services in Aptoide but the Self-check reports: failed: Integrity check, ROM is not clean and Bootloader unlocked. Although I setup the signature spoofing without errors, installing like above.

did you have GApps installed before installing the module?

[RobertoWa]

he is on stock, so original google files are still there.

[nift4]

Huawei devices don't have google apps, he might have debloated them. This is why I asked.

Hello, Sorry, ROM, Stock, as in self-rooted Samsung June update (S21).

[nift4]

Did you manually debloat GApps before installing this module?
