this happens every 4-5 games, client after game just hangs at concluding game

after the game, the client just hangs at "concluding game". happens multiple times in a couple hour period. have to close the client and restart the process. I mean, its 2020 and you guys cant even make a client worth this millennium. I would post an image of the "client hanging" but im not seeing a way to do that. fix your client plz or better yet, upgrade it to match todays technology.
