There was the following error:

Error processing InsertEnter Autocommands for "*":
Error detected while processing InsertEnter Autocommands for "*":
E5108: Error executing lua /usr/local/share/nvim/runtime/lua/vim/lsp.lua:1513:

The remedy was to use gitsigns.lua from @neovim-basic-ide, which omits the following lines (not sequential):

numhl = false, -- Toggle with `:Gitsigns toggle_numhl`
  linehl = false, -- Toggle with `:Gitsigns toggle_linehl`
  word_diff = false, -- Toggle with `:Gitsigns toggle_word_diff`

 current_line_blame = false, -- Toggle with `:Gitsigns toggle_current_line_blame`
 ignore_whitespace = false,
  },
  current_line_blame_formatter_opts = {
    relative_time = false,
 max_file_length = 40000,
},
  yadm = {
    enable = false,
