Nylas is stuck at the loading splash screen on macOS. Console says:

Unlike issue #3343, my Macbook didn't crash this time - it just ran out of battery, and when I started my Macbook up again this issue started.

Showing an error in the user interface and some repair options (reset the database, attempt to repair it, et cetera), would greatly improve the user experience.

Are there any related issues?

Yes, #3343 (also reported by me).

What operating system are you using?

macOS 10.12.3

What version of Nylas Mail are you using?

10.0.48

Do you have any third-party plugins installed? If so, which ones?

No.

Is the issue related to a specific email provider (Gmail, Exchange, etc.)?

No.

Is the issue reproducible with a particular attachment, message, signature, etc?

No.
