Restoring Missing Engine Folder and Organizing Disarrayed Folders in Unreal Engine Project


Previously, there were two content folders and engine folders in my project within the content browser. However, at some point, the engine folder disappeared, and all folders became disorganized. This same phenomenon occurs when I create a new project. Despite attempting various settings adjustments, I am unsure whether reinstalling Unreal Engine is necessary. Is there a method to preserve my existing settings and restore them, or would reinstalling be the most advisable solution?
