I am getting this error from my use of `BlockDiagonals`:

```julia
ERROR: Unsatisfiable requirements detected for package BlockDiagonals [0a1fb500]:
 BlockDiagonals [0a1fb500] log:
 ├─BlockDiagonals [0a1fb500] has no known versions!
 └─restricted to versions * by an explicit requirement — no versions left

```

Whenever I try to add a new package I git this:

```julia
julia> using CSV
 │ Package CSV not found, but a package
 │ named CSV is available from a
 │ registry. 
 │ Install package?
 │ (@v1.7) pkg> add CSV 
 └ (y/n) [y]: y
   Resolving package versions...
ERROR: SystemError: opening file "/home/csidrane/.julia/registries/General/C/CSV/Package.toml": No such file or directory

```

I think it might be because I was in the middle of installing another package and I hit `Ctrl+C` to interrupt it. Maybe my registry is corrupted?

You can just delete it and it will redownload.
