Unable to make inputs during very first hero select

During hero select in a recent competitive game the game seemed to freeze, I could move my mouse according to task manager the game had not crashed but I couldn’t make inputs I was stuck staring as my team complained about an AFK, I tried to join team chat, I tried to type to tell them but I couldn’t do anything. All I could do was leave the game and attempt to rejoin but as it was the beginning of the game when I tried to rejoin the match had cancelled. I looked on the forums and found other decently similar bugs, but nothing where it happened before I even got to select a hero, I wasn’t stuck in the floor I was just frozen but the game didn’t crash and I could hear my teammates firing and using abilities, and I could see them typing about me being AFK but I couldn’t do anything.
