Upgrading from 1.10.3 to 1.10.4 fails on macOS... app starts but no user interface found


Upgrading from 1.10.3 to 1.10.4 is failing and the app runs, but no user interface is loaded. Just a menu with no options.



  • OS and Version: macOS 12.5
    • Installation Method: version 1.10.3 downloaded from main website, and then upgrade using the automatic update from the app
  • Mailspring Version: 1.10.4

Additional Context

Tried to run the app with Apple Silicon too and it fails in the same way.

I can confirm that the problem is related to the spanish language set.

If you install the previous version and then change your settings to use another language, everything works fine.

You may not need to go back to previous version and just change your “config.json” file to set another language:

"intl": {
        "language": "en"

I have just sent a pull request with the fix.

Don’t know when it will be merged. Until then, you should change your config.json to use english or any other language.

Version 1.10.5 was released and fixed the problem :smiley:
