pen sensitivity issue with 680tf

(i apologize if this problem has been solved for eternity now, i could never find it myself im really sorry)
also ill overuse the word sensivity a lot here

• huion 680tf
• drivers work perfectly fine
• ive already tried my tablet on other pc, issue remains still
• this thing is 6 years old so ig its time to go now ngl🥀
• it does have some mechanical damage because a kitten garden sculpture fell on it once, but i doubt it could be relevant since it happened a year ago(as i experience this issue only neow...)
• ive tried different art programms - SAI, paint(+updated ver), CSP
• ive tried charging the pen but it made no difference

the main issue - pen is oversensitive, results in making double taps despite me lowering sensitivity in the driver app settings

the first brush in the vid shows a brush with pressure feature(or wtv its called)

the second - basic pencil brush SAI offers with no pressure trait and the lags here are actually just 75% on the sens bar

as the result - pen becomes oversensitive as i barely touch the surface it still registers as if im pressing on the nib hard (i changed sensivity in the mid of the vid if u couldnt tell)

also, the double tap thing constantly makes these little dots and almost all my lines start rough cuz it thinks im applying some pressure but no!!!!!!!!!!!!!!im jus pointing!!!!boy!!!!!!!!!

and its so frustrating to try to use my pen as a mouse everything jus double taps💔💔💔
