Try

```julia
registry rm General

```

and then

```julia
registry add General

```

and then `up` again.

Do you have a lot of packages installed? I would simply delete the `.julia` folder, and let Julia create a fresh one at next launch.

Hm, it might not think it is a registry because of the missing `Registry.toml`. Try just manually delete the `General` folder.
