So I just recently experienced this issue myself, and after searching through a lot of vague posts I found a solution. Someone referred to it as a "shadow mute", but the solution is to try typing random individual letters or numbers until other players can see your text. Weird enough this bug or mute causes others to also not see what you're typing. Once I typed "1" and sent, it immediately fixed everything.
