POE2, my character Mercenary can't atack with left mouse bottom

Hi, i was playing POE2 for 10 hours but suddenly my mercenary character stopped making attacks with left mouse bottom. Hi still can throw granades and switch patrons with right mouse buttom - but can't attack. I tried to close the game and restart my PC - nothing helps. I play on PC, steam version.
Please help me!

A friend of mine just had this bug and ran around the map kiting mobs while clicking on stuff. Try that. It worked for him.
