Azure DevOps Pipeline vstest.failed even all the unit tests are passed locallt

Question

There are a couple of test.cs files, and one of them totally passed the test in local VS. But when I checked in TFS it starts the CI build in Pipeline where I got vstest errors. I do not know why those tests passed in my local VS failed. Here are my test assemblies and some warning logs.
