It looks like that error is occurring because the file location could not be written to.
Could you check if that folder has write permissions?

Also, if you're using the flatpak or snap package of Pinta, I think there is some additional sandboxing that can sometimes cause issues like this

I think your diagnosis is correct. Thank you.
No doubt you are already working to make the error messages more
comprehensible to the user.
