Cant buy/use Reno air races due to an Xbox account issue

I so want to buy it but my multiplayer features are turned off in my Xbox (adult) account and I cant change them due to an issue…I am tired of getting this message for months now …‘‘we were unable to load your settings at this time. please try again later’’…
Tried to get help from Xbox support but no response…
Tried everything that was suggested from forums all around but no help…
Im on Windows 10 not on a console…
