Regression

[Mono] Unity crashes when calling FindObjectsOfType() with a generic abstract class type that derives from MonoBehaviour

Mono

-

How to reproduce:
1. Open the attached "1312890 repro" project
2. Open the "SampleScene" Scene from the Assets folder
3. Enter Play Mode

Expected results: Unity doesn't crash
Actual results: Unity crashes

Reproducible with: 2018.4.32f1, 2019.4.22f1, 2020.2.6f1, 2021.1.0b9, 2021.2.0a7

Notes:
-The issue only reproduces with the Mono Scripting backend (.NET 4.x and .NET Standard 2.0 Api Compatibility levels). Using the IL2CPP Scripting backend with .NET 4.x or .NET Standard 2.0 doesn't reproduce the issue
-On 2019.4 and 2018.4 streams the Editor and Player crash without a stack trace, only this message:
compute_class_bitmap: Invalid type 13 for field EventListener`1[T]:test
