Firs step restart in safe mode, and try from there.


To start up in Safe Mode,  hold Shift key at Startup. It does a number of interesting things.


I starts to load MacOS, then pauses and does a five minute disk repair, then proceeds. At the end of that it demands you userid and password, even if you normally auto-login.


When loading, it loads only a minimal set of Apple-Only extensions, and does not load graphics acceleration. Screen update will be wonky and slow, but ultimately correct.


It assumes defaults for as many settings as possible, including screen resolution. If you choose to make changes in safe mode, those changes WILL stick in regular mode. So this is a way to get around screen resolution set out-of-bounds, for example. 


Since no third-party extensions are loaded: 


"Works in Safe Mode, but not in Regular Mode" generally implies "It's something you added".

in the article you cited, there is a section about removing your account(s) and adding back in.


Next step, if not stable in regular mode:


I suggest you try removing your accounts, launching Mail, and if now stable, add your account(s) back in one at a time.
