I'm not sure my post should be an answer, glad it worked for op, but after trying both XC beta 2 and then attempting to downgrade to beta 1 neither worked for me. Worked last week fine.

Thanks @brandonK212 that did it. For lines 69 - 103 it was slightly below that for me as well but just replace the section that starts var subscriptions = Set<AnyCancellable>() session.outout with his code and remove subscription from withExtendedLifetime Mine runs, I just copied the folder from the derived data that contained HelloPhotogrammetry ./HelloPhotogrammetry -d full frames/ivy output/ivy.usdz
