My game froze during my round of M21 quick draft.

I was at 4w, 2l yesterday.
Today I logged in, played the workshop event without any problem then I went to continue the draft event.
Game froze and I was force to pass my turn 3.
Turn 4 was heading the same way, so I closed the client and restarted it. After the restart, I was able to play but I could not catch on the tempo loss
