Hi, I have had similar problems. It started out with the Github registry failing to install because of a missing registry.json.zip. I tried creating a registry.json.zip manually using zip (probably not the correct way but I was just tinkering) and then I started getting the Failed to unpack registry archive error. I’m going to try other approaches soon.

@longthanhtran reported a similar problem in mason-org/mason.nvim#1929 (comment)

Seems like the new version (2.0.0) also breaks my lsp inlay_hint, it took me almost a day until I found this issue. Yes, stay with v1 fix my problem.

Here is the error I got when I run 'Mason'

@tandetat , I had built neovim from source and I had not updated it in a long time, updating the neovim, and reinstalling latest versions of all the packages fixed this issue, and also removing "pylint" from mason solved the "registry.json.zip" error.

Thank you for sharing your fix! I was using the latest version of neovim and didn’t have pylint installed, but reinstalling mason and all my packages solved the issue.
