Unreal Actual Uninstall (Not just remove from library)

It appears I have inadvertently deleted files (because Bridge Exporter to Unreal only works with 4.24), so when I start Unreal, it works SOMETIMES, the other time I get several error messages, including:

Plugin ‘UnrealEnginePython’ failed, ‘PythonConsole’ not found. Plugin ‘MegascansPlugin’ failed / not found.

How can I do a fresh install?
Note: I removed Unreal engine and uninstalled from Windows; however after reinstalling, my preferences / errors were still showing up in Unreal.

Please help, thanks!
