I've tried everything the help file suggests, however unable to connect to my friends world.

we are both using the same WiFi network.

We have different Microsoft accounts where Minecraft is each purchased individually.

We were successful in playing until 830PM PST. Then "Unable to Connect to world" bugs are non stop.

I see "Available Worlds" when trying to connect to my friends world.

We can invite each other. We can remove and add each other as Friends on XBOX app. We can reboot the computer. reload data. restart Minecraft. Turn off firewall. All leads to the same error "Unable to connect to world". All help file troubleshooting steps have failed.
