Unable to join realm

I was playing the bedrock version of Minecraft (ver 1.5) when the game and the console froze. After hard restarting my Xbox One I can't join the realm I was on.... the game says I am already playing in the realm on a different device.

Logging in on my son's account, and I can see it is showing me in the realm hours later, even though I am not playing.

The realm owner has since kicked me from the realm and sent me a new invite, which I did accept. But I still cannot join - again getting the error displayed above.
