Issue
Generics are causing the project to crash on startup. Read the following site to get a better idea of why this error is happening https://lostechies.com/patricklioi/2013/12/13/nailing-down-generics/
An issue for this was also created on the Godot repo, which can be found here
Steps to Reproduce
- Download and install either Godot 4 Beta 4 or Godot 4 Beta 5 (make sure you install the c-sharp version of Godot)
- Add the following code to the very beginning of
_PhysicsProcess(double delta)inMovingEntity.csto trigger the dynamic runtime compiler (may not be required, error may happen even without doing this)
int test = 5;
test++;
GD.Print(test);- Run Godot through cmd with
--verboseflag - Select and open Sankari project
- Notice the popup and error logs in cmd
Preview of Popup
clicking OK will close the project

Potential Snippets of Code Causing this Issue
Maybe the abstract keyword combined with generics is the culprit? (https://developercommunity.visualstudio.com/t/cant-run-tests-late-bound-operations-cannot-be-per/692576)
Closed as seems to have been fixed in Godot 4 beta 8
Re-opening as the issue came back. Exact same popup / error.
Seeing a very similar problem with my project, in my case also an abstract class with a generic parameter, but also partial (inherits from a Godot Node)
I removed the abstract modified and implemented empty virtual methods instead of abstract, and when I opened the project, it was possible to see it for a second, then Godot died again.
I went to Visual Studio, cleaned the solution, tried opening the project again, and it worked.
v4.0.beta10.mono.official [d0398f62f]
If cleaning the solution is like deleting the .godot folder then the issue may most likely come back later on.
Looks like this issue is going to get fixed :D
godotengine/godot#70511
Appears to be fixed by beta 11. The error did come back but I'm assuming that's just because I didn't delete the .Godot folder. Fingers crossed.
