I was banned from voice chat?

This is not about the forums. It's the voice chat. When I tried to join voice chat in Game Bar, it closes. When I tried to join voice chat from my Xbox App mobile, it reveals an error.

Radiant Sword X,

If your ban is 24 hours or longer you may request a case review by logging onto the
Enforcement webpage using your Microsoft account information.

Hello Radiant,

Thanks for the updates on your issue. If you checked on the
Enforcement site and do not see a hammer. Then you are not under any ban. This is most likely your system being weird or having corrupt files causing it to close. The game bar will not close due to an enforcement. You will get notification that states something
like "You are unable to use this function due to a temporary suspension". This would only be chat, If it was a permanent ban/suspension, you wouldn't even be able to log into anything Xbox related.

So lets try some troubleshooting for the app. On your phone uninstall and reinstall the app. On the PC we recommend make sure

everything is up to date. Here is a link for
troubleshooting the game bar. On your settings the way you have it, only thing you will get a notification for is an achievement.

Try these and let us know.

Brad

Sadly we aren't able to assist with bans on the forums, you will want to reach out to the MS Enforcement Team, they should be able to assist

It's not just the mobile app, it also applies to the one on Windows 10 PC. Game Bar keeps closing and this could be a virus. As for the main Xbox Console Companion, there is no way to join invites only parties due to the notifications for that being removed
permanently.
