In the middle of a draft game, I alt + f4 to close the application. After that I reconnected. I reconnected during my blocking phase but could not choose my 1/1 human soldier token with one +1/+1 counter on it to block their 2/2 Lightless Evangel that had two +1/+1 counters on it. The only thing else on opponent board was a Illvoi Galeblade. I could not click on either opponent, nor mine own graveyards during this time as well. I tried once more to alt + f4 to close the application and reconnected again but with the same results. After passing the block phase, and it once again became my turn, everything worked again. Next attack phase he once more attacked with his Lightless Evangel, and this time I could block without any issues
