Crashes during play mode start? (worse in 2019.1)

One thing I've gotten used to is having unity crash during play mode start every few hours. But with every update, it's been getting worse - 2018.3 makes it once an hour, and 2019.1 makes it every few play runs. This issue never happens in a build. Also note that between 2018.3 and 2019.1 I made no code changes, and yet the crashes increased.

After looking at logs, I've noticed that the game does actually start - it seems like the first frame or two, at least. Then the editor crashes.

As far as I know, this isn't my own code's fault, right? If so it wouldn't work 90% the time, then not the rest... right?

Here's the error (at least I think its an error) that showed up in the editor log last time it crashed:
* Assertion at ..\mono\metadata\class.c:8808, condition `ac->rank' not met

Is anyone else getting this issue?

 

Same here

 

For me, 2019.3 has made this issue much much much more rare!!
