Neorg treesitter parser fails after update

[LoipesMas]

I've updated my full nixos config, including nixvim, and neorg parser started failing when opening a neorg file.
The error was something along failed to load: Failed to load parser: uv_dlopen: libstdc++.so.6: cannot open shared object file: No such file or directory.
Found this issue: NixOS/nixpkgs#207003
So I tried :TSUninstall all, even though I have the parsers installed by nixvim. It errored about many parsers, saying that they are installed externally, but one of them, norg_meta got uninstalled. When I opened the neorg file again, it got automatically installed and now it works.
Now, my question is, why did that happen and is that a bug in my configuration, nixvim or somewhere else?
