Queue Accept Button Bug

I was in a queue, already waited 20 minutes due to low-priority from an unintentional AFK, and I finally got a game. I hit the button, it said I accepted, then froze. After about 10 seconds the button vanished and said I didn't accept the ready check.

Now I have to wait 20 more minutes and this might happen again.

This bug happens a lot to me on the new client. Draft pick only.
