M1 iPad Pro + iOS 16 + MixEffect Pro = CRASH!

[Update: June 19, 2022] The current App Store version of MixEffect should now work on the developer betas of iOS 16 and iPadOS 16.

In the video below, I get my hands on a brand-new M1 iPad Pro, upgrade it to iOS 16, configure it for use with my developer account, install MixEffect Pro, and watch it crash!

Update: Stage Manager is activated by going to Control Center. See screenshots below.
