--

-

Reproduction steps:
1. Open the attached “repro-project“
2. Open the “Assets/Scenes/SampleScene.unity“ scene
3. Enter Play Mode
4. Observe the crash

Reproducible with: 2023.2.0a10, 2023.2.8f1, 2023.3.0b5
Not reproducible with: 2021.3.34f1, 2022.3.19f1, 2023.2.0a9

Reproduced on: Windows 10, Windows 11 (by reporter)
Not reproducible on: No other environment tested

Notes:
1. Not reproducible in Player
2. The following error is logged in the Editor.log file:

(Filename: Assets/NewBehaviourScript.cs Line: 55)
mono_class_from_mono_type_internal: implement me 0x00
Assertion: should not be reached at C:\build\output\Unity-Technologies\mono\mono\metadata\class.c:2224
Crash!!!

3. Commenting out line “var parameters = methodInfo.GetParameters();“ in the NewBehaviourScript.cs stops the crash from occurring

First few lines of the stack trace:
