Thanks for reporting the issue. Could you please open the application data directory and post the line containing "spellcheckerLanguage" in preferences.json. It should be something like "spellcheckerLanguage": "de-DE", and you could set the value "de-DE" to "en-US" to workaround the validation.

It is set as below. but I should mention after above error, I just installed the "v0.16.0-rc.2" version and have been happy about it.
"spellcheckerLanguage": "en-US",
Happy for this to be closed. As you description above should help someone if they do get this.
