Trying to use Astronvim with master branch of neovim

[Eloitor]

I compiled neovim from source, and tried to use astrovim's default configuration.
Syntax higlighting of a file does not work by default, for example when opening init.lua I need to run :setfiletype lua manually.

Moreover I get this error message:

packer.nvim: Error running setup for neo-tree.nvim: attempt to call a nil value

Is this a problem with packer or with astronvim? Is there any workarround?

AstroNvim does not support unreleased versions of Neovim. Please use a stable and released version.

There are a lot of breaking changes with neovim 0.8 and AstroNvim does not adhere to these new changes. There is the v2 branch that may or may not be working. It's a work in progress getting ready for the Neovim 0.8 release. There are a lot of breaking changes as well that do not align with the documentation. This branch is basically untested and is not guaranteed to work with the latest releases of nightly as new breaking changes happen.

Also it should be noted that currently Neovim nightly is extremely broken when it comes to using winbar which AstroNvim v2.0 does use. So the :split functionality is completely borked and makes the editor pretty much unusable: neovim/neovim#19458

We would highly recommend using stable releases of Neovim.

Thank you, I'm trying to preview latex formulas, which I think is only possible in the master branch: yatli/gui-widgets.nvim#2 (comment)

I tried the v2 branch and I had no problems. Since the master branch of neovim is not supported by AstroNvim, from now on if I have some similar problem I'll try to fix it myself, I'll consider using the released version of neovim instead, or I'll configure neovim myself.
