E10Train Stuck in Single User after failed restore

Tried to push a backup of LIVE into TRAIN slot and it failed saying there wasn’t enough space to perform the operation.

Now E10Train is stuck in single user mode.
single-user

I ran
exec sp_who against master db and don’t see any users on TRAIN.

I can’t click properties on E10Train when logged in as SA. When I do I get this message:
e10-train-properties-error

Does anyone know how to make it not single user mode so I can go to properties on it?

Did you try running a query like this making sure Master is your context

-- Start in master
USE MASTER;

-- Add users
ALTER DATABASE [E10Train] SET MULTI_USER
GO

Wow that worked as easy as that! Thank you.
