Buggy Client, Tons of pop-up messages

After a match, I would get a gazilion error messages saying "A password is required to enter this room". What really bothers me is that it is just straight-up covers the hextech crafting and shop buttons which makes it impossible to make purchases, open my chests, ... Another thing is that if I try to close them 1 by 1, the client would just freeze after I closed 5 of the pop-ups and bug splats. I also noticed that in match-made modes, it does not tell you who entered the chat and at the end of each game, it no longer shows you who got S or everyone in your team honored. Don't know if this is supposed to be a new feature but Riot please, FIX YOUR CLIENT. It is unenjoyable and frustrating at this point.
