I am encountering an error on Julia while trying to install and use Distributions module

Question

I am encountering an error on Julia while trying to install and use Distributions module. I am not facing any errors while installing the module but it displays this error when I try to use the Distributions module. I have no idea what this PDMats or Manifest files are. I'd love to have some advice. Thanks!

This is the entire error:

Answer 1

try Pkg.resolve() or Pkg.update(), if that fails try resetting the Julia registry
