While playing games, characters walks by itself

Hello,

When I connect to server (or start streaming) and start some game (DBD, Apex Legends,...), the character walks by itself for certain period of time. I push W and nothing happened, but after a while character start walking and cant stop I can only use mouse. I dont know what to do with this. This never happened to me, i recently updated to WIN 11, so could be problem there?

Thanks for answers.
