3th time Huntsman V2 TKL is not working correctly anymore after updates

this is now the 3th time in a row i have problems with this keyboard. 2 times i got already a new replacement under warranty and this one is also not working. It doesnt matter where i connect it to but it seems after some updates the keyboard doesnt work correctly anymore. When i lift it up and put it down it suddenly makes a screenshot, when i want to type something, a lot of keys are sticking and there is a massive imput delay sometimes what causes my pc to crash in memory. 

I dont know why this is happening but i am getting tired of this keyboard when it is now 3 times broken in a row.
