If you enter the game and do not use and text features (opening chat or inventory) you will be able to use space bar to jump, however if you do use these the spacebar will seemingly just stop registering the press and will not jump, if you set the keybind to anything else it will still jump however you then cant set the keybind back to space.

if this issue could be fixed that would be nice as it severly impacts gameplay not being able to use the spacebar to jump.
