Windows searchbar keeps popping up,

my dad bought me a chuwi hi 10x for my 14th birthday,
and when i got it, its ok
but when the months go by i experience ghost touch etc
i disabled the touchscreen, cuz i cant find any other fixes,
also, theres this thing that keeps bugging me
the windows searchbar keeps popping up,

I own the keyboard, and stylus
usually it pops up when i bob the head up and down,
and if you remove the keyboard tablet will go crazy keeps popping up
drives me crazy

(im not a computer tech also im quite young, so i dont know if im allowed to open up the tablet, since dad’s going to be mad lol)

Thank you so much in advanced

ps: i need it for my drawings and school :’) so help is appreciated
