Looks like something is going wrong with saving the current palette to the preferences folder
For Windows this is something like "%AppData%\Roaming\Pinta" I think - does that file exist / have appropriate permissions? Although it looks like the error message is something to do with the file name so it would be useful to see what the path of that folder is on your system
