"Error detected while processing WinLeave Autocommands for "*"" when closing Lazy window

[oschrenk]

Describe the bug
I use lazy.nvim [1] as my plugin manager. I noticed a few errors when using it with gruvbox.

1. Open Lazy with :Lazy
2. Close with :q

Get error:

Error detected while processing WinLeave Autocommands for "*":
E21: Cannot make changes, 'modifiable' is off                                       

This does not happen if gruvbox is not loaded

Expected behavior
No error message closing

Additional context

I also notice an interaction issue with [2] which might be the same underlying issue. When I move out of the neovim window with Lazy open, I get

E11: Invalid in command-line window; <CR> executes, CTRL-C quits

but only if gruvbox theme is loaded (as opposed to caret for example).

I still don't know what the issue is but I don't have proof think it's the theme. I was loading plugins one by one and the issue appeared when gruvbox was loaded and then didn't appear when I loaded caret via :colorscheme caret . But now when I load caret via Lazy

return {
  "projekt0n/caret.nvim",
  lazy = false, -- make sure to load this during startup
  priority = 1000, -- make sure to load this before all other plugins
  config = function()
    require("caret").setup({})
    vim.cmd("colorscheme caret")
  end,
}

It also happens with caret. I need to investigate more
