I believe it is expected that there will be exceptions with Xcode 16 currently until support lands in November.
#24819.

Perhaps this issue can be closed for now and reopened later when support is added if this is still an issue, or can be left here brought back up in November, thanks!

As for debug on MacCatalyst, this issue also repro on MacOS Sequoia 15.0, not repro on Mac Sonoma 14.6.1

Seeing the issue here, we still use Mac Sonoma but with Xcode 16.0, the app deploys but crashing immediately, I'm not to sure on the steps to roll back our MAUI workload either, although we updated to latest them at the time due to some other issue that I can not remember.
