Setting fontsize causing error

[idelice]

Describe the bug
I tried setting the font size in my init.lua:

if vim.g.neovide then
  vim.g.neovide_transparency = 0.6
  vim.g.neovide_window_blurred = true
  vim.g.neovide_unlink_border_highlights = false
  vim.g.neovide_refresh_rate = 120
  vim.g.neovide_remember_window_size = true
  vim.g.neovide_show_border = false
  -- vim.g.neovide_floating_blur_amount_x = 2.0
  -- vim.g.neovide_floating_blur_amount_y = 2.0
  vim.g.neovide_floating_shadow = true
  vim.g.neovide_floating_z_height = 10
  vim.g.neovide_light_angle_degrees = 45
  vim.g.neovide_light_radius = 5
  vim.o.guifont = ":h11" -- text below applies for VimScript
end

and I get the following error when opening a new neovide instance:

Expected behavior
I expect the font size to be changed to the one i set and receive no errors.

You need to specify a font name before :h11, you can check available fonts with set guifont=*

I've already tried that and a couple of other suggested solutions from Reddit but none worked... can you please provide me an example of only changing the font size?

To change the font size you can you the neovide_scale_factor option. There are some examples in this discussion #2301 (comment)
