Crash from LSR

[builder-main]

Hi Chris,
We found there are crash from here
in LSR, DynamicCompilationBase.cs:66

AssemblyCsharpFullPath = SessionStateCache.GetOrCreateString(
                $"FSR:AssemblyCsharpFullPath", 
                () => AssetDatabase.FindAssets("Microsoft.CSharp")
                                .Select(g => new System.IO.FileInfo(UnityEngine.Application.dataPath + "/../" + AssetDatabase.GUIDToAssetPath(g)))
                                .First(fi => fi.Name.ToLower() == "Microsoft.CSharp.dll".ToLower()).FullName

`Sequence contains no matching element

Microsoft.CSharp wont find anything in assets as FSR is in package

We tried this
() => AssetDatabase.FindAssets("Microsoft.CSharp", new string[]{ "Packages", "Assets"})

from https://discussions.unity.com/t/assetdatabase-findassets-not-working-for-packages/707087/10

But seems it was not enough and it still can't find it, we're on unity 6.1.14f1

Crazy that it'll crash it. I'd imagine it'd be just exception
Should be easy fix just not using AssetDatabase.FindAssets

It's crashing the worker thread yes. But the importer is really unstable and we get regular worker thread crashes from other things as well. I removed LSR atm and I still get worker crashes but I got no more editor crashes.

I'd advise using FirstOrDefault or to test that we indeed retrieve a value to avoid exceptions
