R KEY PINGING " FALL BACK " RANDOMLY AT IMPORTANT MOMENTS

hello everybody!

i'm experiencing this bug since at least 3 months, i thought it was the keyboard but i just bought a new one and it happened again. the bug reveals itself mainly on champs like Riven,Yasuo,Darius and also on Jhin/Xerath sometimes, basically champs where I tend to press the R key a lot it's pretty annoying because I'M NEXT TO ENEMIES WITH DARIUS DO THE FULL ROTATION ON 3 OF THEM AND WHEN I'M LIKE " SWEET I'M GONNA DUNK EM AND RESET A LOT " it fking START PINGING TO FALL BACK FROM ENEMIES with the R CURSOR VISIBLE AND DOES NOTHING. Usually my team enjoy the free kills, but sometimes it messes up proper set ups turning them into tragic and comedy at the same time. I also had to apologize to my team sometimes 'cause they were like " why are you pinging? can you stop? report him :( " IS SOMEBODY OUT THERE EXPERIENCING THIS STUFF LIKE ME ? DID YOU FIND A SOLUTION ? i also tried switching the USB port but saw no changes, I cancelled all the quick pings leaving just the G key and I did the LEAGUE REPAIR twice
