Good morning. A member of the legion has problems with the keyboard within the game, that is, she cannot type. The keyboard is fine and in other games it doesn't have that problem. Use Windows 10.
We already checked in other games and it has no problems. Could it be the Anti Cheater? is there another way to validate it?
She uses the game downloaded from the launcer and from the beginning she had this problem with the game. The keyboard was revised and it is fine, in windows everything is fine

Hello,

Does the problem persist? Have you tried using another keyboard? 

It's probably a program that's running in the background... If you run AutoHotKey for example, the game won't register your inputs due to the anticheat
Try looking through task manager and see if there's any sort of software that might trigger the anti cheat  such as AHK/Other macro programs
