Stuck unable to install or uninstall GMSCore

I used to have RVX before uninstalling it, but after trying to repatch and reinstall it, I've been completely unable to use MicroG services. If I try to install the latest gmscore release from GitHub, my phone detects the app as already being present as an older version on my phone, even though it's not present in the app or packages list.

Running adb shell pm uninstall -k and then app.rvx.android.gms does not work as the phone does not detect the packages.

Can I even do anything other than resetting my phone?

Using inotia00's RVX manager if that helps
