Unreal Engine Not Updating for Code in a certain Project

I’m having an issue with a certain project of mine not updating inside Unreal Engine with the new code I build unless I restart Unreal Engine. The process is as goes, I change code, I hit Build Solution inside my Code Editor (Rider), I hit Compile button inside Unreal Engine, and the code is not reflected. However, when I restart, the code changes are implemented.

Inside Unreal Engine => Project Settings => Packaging => Build Configuration => Development.

I did however, try creating a new project just to test, but it seems working in this new project. Any ideas on what could be the problem with this particular project?

I am using
Unreal Engine v4.26.2 and Rider for my Code Editor
