How do I save my assets in project with sufficient permission warning?

Hello,

I am trying to import and save my textures in my Unreal project but every time that I do, I receive the warning: You do not have sufficient permission to save the following content to disk. Any changes you make to this content will only apply during the current editor session.

I am using version 4.20. I do have version control setup with Github. Some texture files both local and from Github do not import into the content browser of the project. However, the textures only show up in windows explorer as a uasset.

I have tried checking in windows explorer if the project files are marked as read only but they are not. Reading other similar issues, I disabled windows defender as well but still the problem persists. I also tried changing UAC control with the same result. I thought about migrating the files to a fresh project if this current is bugged but none of the uassets can be accessed in the content browser of the new project.

Any help would be much appreciated.
