This is becoming annoying.
Happens on a daily basis now, and has for a month or so (using 2018.2.x.
I never encountered it before 2018.2 (or so rarely I never noticed it).

Related but unrelated. I get this same crash message in the log in windows standalone build when I run the build when built with 2018.2.5f1 but it works fine when built with 2018.2.3f1
Callback registration failed. Increase kMaxCallback.

Tried the latest 2018.2.5f1 which claims to fix the issue, however unity crashed and quietly closed with no error at all this time. It never did so like this in previous versions so it could be related or simply a bad fix.
