I had to reinstall Eclipse because I somehow broke something. But that’s not the main issue. Before uninstalling everything, I made a copy of the entire Eclipse workspace folder and stored it in a safe location. After reinstalling Eclipse, I recreated the Eclipse workspace folder and then moved all my saved files into it, along with the .metadata folder and other necessary items. However, when I start Eclipse, it doesn’t appear in the package manager.

Even when I try to import it through “General” and every available option, the files don’t show up in Eclipse to be added back into my package manager.
I already looked through a lot of different questions here with people who had the similar problem but nothing in their solution helped me
