That's what I assumed. So I deleted microg, rebooted, then downloaded and installed the one from the link in the OP. Then rebooted again. I even tried uninstalling yt Vanced and reinstalling it.You must have the microG for Vanced. No other microG will work for Vanced non root. It is made specifically for this app. Try re installing.
The microG for Vanced lets me attempt to add my Google account, but stalls while contacting Google. Neither version of microg allows me to use the Google account already on the phone
