Getting rid of .dismiss is also what fixed the infinite loop behavior for my project. FWIW, if I changed the navigationDestination to a sheet it worked fine, except of course I don't want it to show in a sheet.

My apologies if this post came across as frustrated and harsh. I just want Apple to address this need in a reasonable way. Also, to provide real guidance for how to handle the situation, that every app developer needs, of some background processing in a reliable way.
