From one minute to another, my installation of Julia cannot add packages anymore. I tried reinstalling Julia but to no avail. How can I fix this?

```julia
(@v1.5) pkg> add DiffResults
  Resolving package versions...
ERROR: Unsatisfiable requirements detected for package DiffResults [163ba53b]:

You (probably) have a broken or non-existing registry. Try to remove and add again:

```julia
# Remove
rm(joinpath(DEPOT_PATH[1], "registries", "General"); force=true, recursive=true)
# Add
import Pkg
Pkg.Registry.add("General")

```

That worked, thank you so much!
