Is anyone else having this glitch ?

Basically i lost a few of my runs bc of my game just freezing then automatically spams inputs i did few seconds prior, and sometimes it doesnt freeze but lets say i press "z" once it spams it for no reason. Sucks when for exemple your attack it spams its weak against the type you're fighting. AND WORSE WHEN YOU HAVE A MOVE THAT IS SUPER EFFECTIVE AGAINST IT TOO.
I didnt saw any post and im using opera gx (bc my google is brain dead rn). Please im about to lose my sanity lol
