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.
