Reproduction steps:
1. Create a new project in 2022.3.X
2. In the Package Manager install the Entities (com.unity.entities) package
3. Download and import the attached package “ReproPackage”
4. Observe the Console Window

Expected result: No errors in the Console Window
Actual result: The error “Burst internal compiler error: Burst.Compiler.IL.Helpers.MethodDecoderException: Unable to decode `__UnmanagedPostProcessorOutput2943707651, Test.Runtime, Version=0.0.0.0, Culture=neutral,_” is thrown

Reproducible with: 1.8.8, 1.8.10, 1.8.11 (2022.3.16f1, 2023.2.4f1, 2023.3.0a19)
Not reproducible with: 1.8.10, 1.8.11 (2023.3.0b1)
Couldn’t test with: 2021.3.33f1(The user’s package errors)

Reproducible on: macOS(Intel) 14.0 Sonoma
Not reproducible on: No other environment tested

Notes: Although the error is clearable in the Console Window it reappears every time a script is recompiled.
