Big Sur skillz

We are making Skillz and Apple games.

1. We are having problem during Apple build.

I developed the game by applying the skillz sdk with Unity and installed it on the test iPhone through xcode, but it ended immediately.

1. Install the Big Sur operating system from MacBook.

I'm trying to get a crash log file.

So if Big Sur has any problems with this.
I want a solution.

unity version 2019.3.12 / sdk_unity_crossplatform_26.2.9_26.2.9/ macos big sur ver 11.2.3 / xcode ver 12.4

please. help us~
