Crash occurs during search (possibly scripting runtime related)

[TimmermanV]

A crash occurs when using Scripting Runtime .NET 4.x Equivalent in Player Settings. No crash occurs when Scripting Runtime .NET 3.5 is used. Reproduced the issue 5 out of 5 times searching for audio clips and sprites. I left all search settings on their default values.

I'm using Unity 2019.1.8f1. The latest version of TextMeshPro requires .NET 4.x, so switching back is not an option for me unfortunately.

Here's the call stack of the crash:

Apparently, System.Reflection.Assembly variables cause this issue on .NET 4.0. Should be fixed in 64408e3

Awesome. Thanks for the quick fix. Everything seems to be working now. And this new version appears quite a bit faster. Great!
