@lewing the ordering in your ErrorMessage array matters. In the log geckodriver INFO occurs before fail: System.TypeLoadException so the order in the query needs to swap. I fixed it.

Log

System.TypeLoadException: Could not load type of field 'Mono.Options.OptionSet:ValueOption' (3) due to: 
Could not resolve type with token 0100002f from typeref 
(expected class 'System.Text.RegularExpressions.Regex' in assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51') assembly:netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 type:System.Text.RegularExpressions.Regex member:(null)

Do we need memory barrier after we load the assembly from fetch ?

I thought lot of those issues are only visible on FF, but here we have Chrome specimen.

Log

[09:18:53] fail: [0x000ebcc8--UI- 09:18:53.626] MONO_WASM: Could not set up parent class, due to: Could not load type of field 'Xunit.Xunit2Discoverer:<TestFrameworkAssemblyName>k__BackingField' (7) due to: Could not load file or assembly 'System.Reflection, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. assembly:xunit.runner.utility.netcoreapp10.dll type:Xunit2Discoverer member:(null)

                    at Microsoft.DotNet.XHarness.TestRunners.Xunit.XUnitTestRunner.Run(Assembly assembly, String assemblyPath)

That means it's our problem, not FF
