Compile all Blueprints

As of 4.22.1, CompileAllBlueprints crashes all the time (even in a brand new empty project). I just filed a bug for it so I don’t have a UE-XXX issue number yet. More information here:

The issue is UE-73069. It has already been fixed in github sources and is targeted for 4.22.2.
