I just re-installed JuliaPro - that was working before - and now when I try to add a package I get this error

Any idea of why? thanks

Assuming you didn’t intentionally make any changes to your local registry: Delete `~/.juliapro/JuliaPro_v1.2.0-1/registries/` and restart JuliaPro.

Didn’t help. I deleted the content of registries and then the folder itself, and still get
