Unable to press play button occasionally![Client]

Every now and then when I am in the client either waiting to play or just have it open and happen to realize it my play button grays out and I cannot press it. The only way I have found a way to fix it is restarting the client. I am also pretty sure if you wait long enough it will come back but the quickest is a restart. I am not sure if there is something I am doing that makes it happen or it is completely random. It happens like 3 times a day and it gets annoying.

Update: Apparently it also happens if you press play and leave the screen up for awhile without choosing a game mode, and when you finally do it says an unexpected error had occurred.

Update 2: Logging out will not fix it sometimes now
