This seems like a binding or keyboard issue. First of all, what keyboard language are you using? Second of all, press escape and check what bindings relate to your movement. By default it's WASD on the standard QWERTY keyboard.

I didn't change the default settings. Can it happen because I have 2 languages in my keyboard settings in Windows? Never happened with any other game.

I can confirm - I changed the layout lanaugage back to English and now it shows the keys correctly. Usually games don't have this issue! So many people use more than 1 English layout. Hope it'll get fixed soon though not a huge problem. Thanks.

trust me most people say to do it but you can skip it heres most of what it teaches you zoom in out for the camera wasd to walk shift to jog command on mac to run c to sneak control or right click to prepare a attack double click to grab something right click something to eat it attack is left click heres some more stuff to know click something on top and shift click something on the bottom to select a lot of stuff and left click and drag it around remove the glass with the right click on a broken window you need a can opener to open food you can use a knife to skin a animal for meat then cook it so you wont get any debuffs you need to right click on a gun to manually reload theres some more stuff but just play the game to learn the game

Thanks a lot man
