Realm not being able to play but others are and is on the right version.

When i tried to jump on a realm which was updated and other people on 1.14 has be able to join. me and one other is having trouble like this.

Not sure if its anything realm but i wanted to make sure?

Selecting it and the play button doesn't work, double clicking it doesn't work and as you can see with  the other two photos it is selected behind me and its saying im licking the green wording which isn't even there.
