This is not a issue or a bug, but a lazygit thing. If you want to work within nvim with lazygit, you can add the following in the C:\Users\user\AppData\Roaming\lazygit\config.yml file,
OR
use the :LazyGitConfig option directly within nvim after installing and initlaizing the kdheepak/lazygit.nvim which opens the C:\Users\user\AppData\Roaming\lazygit\config.yml file:

os:
    editCommand: 'nvim'
