Keyboard issue with No Man's Sky on Linux?

Has anyone playing on Linux tried to use the Text Formatting Guide?

When I try to do it on Linux, every time I type < it gets replaced with >. So I can't do symbols or colors etc. I tested on my desktop Xubuntu (fails), steam deck (works fine using virtual keyboard), and windows 10 pc (works fine).

I am using a standard generic 105 key keyboard, the < key works elsewhere.
