Started happening to us when upgrading to 2021.3.37. It's weird because this bug is marked as fixed in 2021.3.36f1 but it's listed as a known issue in 2021.3.37.

Apple has flagged our app and warn us that we won't be able submit an update unless new version addresses this issue. This critical for us.

Problem is continue on Unity 2022.3.22f1. We have gotten too many crashes

Same problem at 2023.3.35f1... and STILL CAN reproduced on 2023.3.36f1...
idk why this issue is so 'stubborn' to be fixed...

Have the same problem at
2022.3.19f1

We also got this issue when we updated to the Unity 2020.3.34f1. On different projects, the stack trace is different, but I assume the roots are the same.

I can confirm this is still occurring for me on iOS and MacOS using 2022.3.21f1 sadly.

Seems like this issue is back in the known issues of 2023.2.14... Also, it appears that the release notes for 2023.2.13 are now saying that an exception is thrown when it originally claimed it was fixed.
