I can't save any changes to the board configuration.
Back story, I've been trying to add a new column for weeks, it fails I try again later, repeat.
The error:

Our board just has 3 columns and some extra statuses.
It's not just adding columns that won't save, I can't save ANY CHANGE including column names etc.
Is my only choice really to abandon the space completely and start over? Because if that's the case I'm probably switching to linear haha
