The active test run was aborted. Reason: Test host process crashed

Description

For a defect reproducable from the vstest command line, describe the issue you’ve observed.

Steps to reproduce

1. git clone https://github.com/xuzhg/WebApi.git git checkout -b RoutingBaseForNEtCore30 origin/RoutingBaseForNEtCore30

2. dotnet --version

3. run the following command (please replace the following Folder): dotnet test [YOURLocalClonedFolder]\test\E2ETest\Microsoft.Test.E2E.AspNet.OData\Build.AspNetCore3x\Microsoft.Test.E2E.AspNetCore3x.OData.csproj --logger trx --results-directory C:\BuildAgent\_work\_temp --configuration release --no-build -v diag

4. result:

Expected behavior

Shall pass all test cases running

Actual behavior

Crash with the error message:

only installed VS2019 Enterprise.

Additional Info

If i run the failure test case individually, it can pass:

We are getting this issue from time to time on our build server, too. It’s not consistent and sometimes it works just fine. We didn’t see before when we were running core 2.2, but now see when we are running 3.1

[adaughterson]

We are using vstest indirectly (via Microsoft.NET.Test.Sdk), and I have upgraded it to 16.5.0, and yet the error persists.
