Plugins not properly functioning on fresh install until "PackerSync" is run and treesitter runs background update.

Reproduction steps:

clone_if_not_exist "https://github.com/luan/nvim.git" "${HOME}/.config/nvim"

# Add custom Nvim config
echo "Symlinking nvim config"
rm -f "${HOME}/.config/nvim/lua/user/after.lua" "${HOME}/.config/nvim/lua/user/plugins.lua" "${HOME}/.config/nvim/lua/user/before.lua"
mkdir -p "${HOME}"/.config/nvim/lua/user
ln -sf "${DIR}/nvim-after.lua" "${HOME}/.config/nvim/lua/user/after.lua"
ln -sf "${DIR}/nvim-plugins.lua" "${HOME}/.config/nvim/lua/user/plugins.lua"
ln -sf "${DIR}/nvim-before.lua" "${HOME}/.config/nvim/lua/user/before.lua"

# Update all the plugins
nvim +UpdateRemotePlugins +qall
nvim -c 'autocmd User PackerComplete quitall' -c 'PackerSync'

At this point the plugins are partially working, but opening up a tree navigator - results in an error:

It's not until a :PackerSync is manually invoked does the treesitter begin to get updated as a background process.

Note "60/70" in bottom left corner indicating an update is occurring even after the :PackerSync is finished.

I was able to reproduce this. And got around the problem with a nvim -c 'TSInstallSync all' -c 'qall'

Can you try that and see if it fixes it for you too?

nvim --headless -c 'TSInstallSync all' -c 'qall' fixes it. When using it without the headless it causes nvim to kick in with a pager of some kind.

Thanks!
