MSBuildWorkspace.OpenProjectAsync() does not load anything

This is likely another instance of #73854

@JoeRobich I think this is the new extensibility model, so it would be something else (although possibility a similar root cause)

@gamadori-osm: if you attach an event handler for MSBuildWorkspace.WorkspaceFailed, is that event fired? Any failure absolutely should result in your task not waiting forever, but maybe we have multiple bugs.

@jasonmalinowski I've tried attaching an event handler but the behaviour does not change. The handler is never fired.

@gamadori-osm Hmm, strange. And if you don't do the MSBuildLocator at all, does that change anything? if you're still seeing the hang, what might be helpful then would be to grab a memory dump of the process once it's hung and if you can share it. We can debug from there.
