Mailspring error after update

Help
#1

Mailspring showed an update option. I clicked it, but then got a repeating error message. Deleted the app and reinstalled it, but still get repeating error message. See screenshot for details. How do I correct this?

I was enjoying Mailspring, and don’t want to go back to other apps I’ve tried.
