Why can't I send chat in game?

Not sure if this is a keybind issue, nobody responded to my request for help with finding the key config file… but this is my main issue: I cannot send chat in game. I can hit T, and the box pops up, and I can type in it. The problem is when I hit enter, nothing sends. It just kind of locks things up and I have to hit escape to do anything again. I found someone posted on steam about this but there was not resolution to it… Anyone know how to solve this?

Having the same issue here. thinking I may have to reinstall the game or something…

not sure what it is, but given that the chatbox comes up i think you can rule out keybind issues.
