this guy scammed me in skyblock he said he will help me finish my huge island but when i made him co builder he took my cross slash and left the game. if you cant ban him please get me my cross slash back i spent alot of g cubes on it

my friends cant join me in sky block and bedwars doesnt work because i dont have the update but im on pc so i dont know how.
i am not using an emulator

whenever i try to go into bedwars i get to the lobby but there is nothing on the screen except for where the swords are and when i press solo nothing pops up it usually tells me do you want to start game but now it doesnt say that.here is what it looks like(

i dont know how to cap my clicks per second

when i click fast my sword sometimes doesnt attack people in bed wars and i tried with multiple mouses it never worked so fix this becausde when i go over 4 cps my sword doesnt attack
