PC [HELP] D (walk right) key now working - "already bound" - Ubuntu 20.10

[PenTemma]

D key will not walk the player right. When I re-bind the action to any other key, walking works perfectly. However, when I try to rebind the action back to D, I am told that the "Key is already in use".

I have tried uninstalling and reinstalling the game, with and without Steam sync.
This happens across save files, even new save files from reinstalls.

Even when opening up a save file and searching for duplicated keymappings, I can only find one mapping for "D"

Any help would be much appreciated!

Just made an account to report that I'm having exactly the same issue. The bug appeared in Ubuntu 20.10 and is still present in 21.04.

I remember that this bug didn't appear after I first started playing, only on the second startup. I also recall that I somehow managed to temporarily fix it by removing all files from disk and reinstalling, but I can no longer reproduce it.

Any help and suggestions would be deeply appreciated!
