Dotnet test hangs when running on a multi-project solution

I've just upgraded to dotnet 2.2.300 and since the upgrade I've started experiencing a problem running unit tests.

I have multi-project solutions which store all unit tests in a dedicated subfolder, and when I run dotnet test in the solution directory the test project hangs with the following output:

ram@localhost:~/development/Foo$ dotnet test
Test run for /home/ram/development/Foo/tests/Foo.Core.Domain.Tests/bin/Debug/netcoreapp2.2/Foo.Core.Domain.Tests.dll(.NETCoreApp,Version=v2.2)

Oddly enough, if I run dotnet test within the directory of each unit test, everything works as expected.

Here's the output of dotnet --info:
