Why can't I invite friends to any game on Xbox?

Game invites have been hit and miss recently, albiet my experience is only of Forza Horizon 5...a streamer I race with often has issues where people don't receive their invites and someone else has to do it for them...the other day I wasn't receiving invites but it was resolved by restarting the console

Hi I've been playing Minecraft on ps4 with my friend who plays on switch, I can see everyone as online and Join their worlds just fine, However when they try to join me It doesn't let them accept my invites and It also doesn't show me as online. I have restarted my router my play station and my friend has other ps4 players join their world so I know it's a problem on my end. I haven't a clue why it's happening but it would like it to be resolved

Hi MunckinBunny#1! My name is Ricardo an independent advisor ready to help you with this situation!

Please perform a power cycle reset, follow these steps:

Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

Restart your Xbox One console. Press and hold the Xbox button in the center of your Xbox One controller to open the Power Center. Select Restart console and then select Restart. (If the console appears to be frozen, press and hold the Xbox button  on the console for 10 seconds, until the console turns off. After the console shuts down, touch the Xbox button on the console again to restart.)

After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

If you are using a router, plug in the router and wait for all the lights to return to their normal state.

And why you thing i don't try that?

I try that without any success.

To invite someone at your game it must first added as friend if you don't added as friend then YOU CAN'T invite him is so simple.

And this is happening from monday.

I got invited also and I can't view the private forums either and I also can't join any friends party's or send party invited to my friends on xbox
