Strange message if test fails with preview 5.0.100-preview.2.20176.6

See original GitHub issue

If a test fails I get strange output at the end of tests for a test project

C:\Program Files\dotnet\sdk\5.0.100-preview.2.20176.6\Microsoft.TestPlatform.targets(32,5): error MSB4132: The "Microsoft.TestPlatform.Build.Tasks.VSTestTask" task returned false but did not log an error. [C:\git\coverlet\test\coverlet.core.tests\coverlet.core.tests.csproj]

It doesn’t happen if I pin sdk to 3.1.201
