--

-

How to reproduce:
1. Open project "1422009"
2. Open Edit -> Player Settings -> Player
3. Set Scripting Backend to IL2CPP
4. Open File -> Build Settings
5. Build the project
6. Observe the Console

Expected result: project builds successfully
Actual result: project build failed with the error "IL2CPP error (no further information about what managed code was being converted is available)"

Reproducible with: 2021.3.4f1, 2022.1.3f1, 2022.2.0a12
Not reproducible with: 2022.2.0a13
Could not test with: 2019.4.39f1, 2020.3.35f1 (couldn't clear or fix errors in the console window before build)

Reproducible on: Windows 10 Pro

Note:
-There might be other errors than mentioned before but ignore them.
-Issue only appears when building in IL2CPP Scripting Backend
-Error first lines:
IL2CPP error (no further information about what managed code was being converted is available)
System.AggregateException: One or more errors occurred. (Value cannot be null. (Parameter 'definition'))

    We also confirm that 2021.3.9f1 doesn't fix the issue. Please fix!

    2021.3.9f1 doesn't fix the issue. It still throws an `ArgumentNullException` inside `Unity.IL2CPP.DataModel.dll`.

    ```

    Сan not update Unity from version 2018 to version 2021 for Android 13 support. And there is no information on how to solve this problem. Without access to the source code, it is unlikely that I will be able to solve it. So hope only for this ticket.
