I’ve been getting this bug for a while, when I spawn in to any game I cannot move at all with my keyboard if I have my controller plugged in. I can move with my controller. If I reset I am then able to use both my controller and my keyboard, but it’s annoying and took me a while to realise that it was due to having a controller plugged in, which I use a lot for testing.
More info:
OS: Windows 10 - been happening through multiple updates
Controller: XBOX One controller wired USB (an official one)
Please don’t hesitate to ask me anything if I’ve missed detail here.
