Mason is Broken

Mason is not working with the new update

I had a similar issue with the new mason update. I was able to fix it without downgrading by changing the config inside of lspconfig.lua.

Replace the mason_lsp.setup_handlers section with this:

                     vim.lsp.config("lua_ls", {
			settings = {
				Lua = {
					runtime = {
						version = "LuaJIT",
					},
					diagnostics = {
						globals = {
							"vim",
							"require",
						},
					},
				},
			},
		})
		require("mason").setup()
		-- Note: `nvim-lspconfig` needs to be in 'runtimepath' by the time you set up mason-lspconfig.nvim
		require("mason-lspconfig").setup({
			ensure_installed = { "lua_ls" },
		})

Update:
All you really need to do here is replace mason_lsp.setup_handlers with mason_lspconfig.setup()
