Mail app icon won't open.
Anyone know why my mail app on macbook pro, 15", 2017, won't open? The icon is not the envelope icon but is the stamp icon. Am running 10.13.6 high sierra.
MacBook Pro 15″, macOS 10.13

Open Applications & try opening it from there.
If no go...
Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.
Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.
