Unable to launch tests in Xcode 26

I am trying to upgrade my app to use Xcode 26 and I cannot get my tests to launch.

I am trying to launch tests to the simulator, and I always get this error after 300 second timeout: "encountered an error (The test runner hung before establishing connection.)"

There are no other errors getting logged.

I can run to the same simulator just fine, and in Xcode 16 the tests launch with no issues. The tests also run fine on an actual iPhone.

Thanks in advance.
