I’ve managed to reproduce this on two entirely different machines and dev installs.

Steps to reproduce:

1.Start Discourse locally with: `EMBER_ENV=production bin/ember-cli -u` (though Ember ENV doesn’t seem to change things here)  
2. Ensure there are no third party plugins or Theme Components installed.  
3. Navigate to Admin → Customize → Theme  
4. Create New Theme Component  
5. Attempt to add some CSS  
6. This results in blank page and this error in the console:

`Error: ember-computed-decorators does not support using getters and setters`

@David if I check out just before this, everything is fine …

Think I’ve found the offending line:

The fix is live now. If you updated your site during the hours when it was broken, you’ll need to run another update now to get things working again.

thanks @David … I was in the process of creating a PR, but appreciate the rapid response, you’ve saved me lots of time: it would have certainly taken me longer! 😅
