Realm server crash when switching from mini game to regular world

When I gained access to my realm, I started with a mini game (Dash of doom 1.1) and everything worked until we tried reverting back to realm where it crashed and became unusable. The face next to the realm is all pixelated and i cant even restart or close the server as the buttons only respond rarely. I hadn't even paid for the realm 5 minutes before the realm stopped working. The estimated wait time is 15 days on the support center, and this is half of what i paid for.
