I have https://github.com/practicalli/nvim-astro5/pull/61 which I am very happy with, properly supporting the newly released Neovim 0.12. This incorporates changes in 0.12 underlying API for treesitter and lsp, with improvements from AstroNvim v6. I have disabled neo-tree plugin and using Snacks Explorer instead, which should be the only noticeable change from the end-user point of view. I will do some more testing tonight and merge the pull request tomorrow.
