Revit 2024 fatal error while running the addin

I have developed the addin for Revit 2022, it is working fine on this version. When I am trying to test on the 2024 it is giving the following error in the image.

I don't know the reason of this failure. You can try to run your code into parts in try-catch exception handlings. So you can determine which part of the code cause this error.

you probably didn't put some needed dll in folder, or because it is core dll you probably miss some runtime files that is for this specific platform.
