Multiple Bugs in TFT

Game loads, I have maybe 2 seconds to pick a champion before it auto picks for me. I spawn in way after everyone else, I can hear them emoting and moving and picking their champs, but I don't get to choose until the very last second.

After I lose, I can't exit the game. It just freezes for about 15 minutes or until I force shut down League Client and then it freezes for about 5 minutes.

When you try to quickly sell a champion it will very rarely sell a different champion at random. I tried selling a unit I had on board before the round ended and it sold another one of my champs. Wasn't even near the champion I was trying to sell so it was not a misclick.

Items randomly appearing and disappearing throughout the match, not sure what causes this.

Champion AI is buggy, sometimes my characters are just standing still not doing anything even when taking damage. Sometimes they try to path to a champion really far away and just take a ton of damage for free while they run. Im not sure how they determine what champion to attack but it seems like they will sometimes just not attack a low health target or randomly switch off a low health target to attack a healthier champ. This has lost me quite a few rounds.
