Steps to reproduce

Install using Packer and run it with config.

Expected behavior

It doesn't break my config.

Neovim version (nvim -v)

0.9.5

[Barmaley0]

Yes, everyone has such problems. Roll back to the old version. And everything will work. tag = "v3.5.4"

Duplicate of #869

Latest version should work with 0.9 again. But I make no guarantees, this plugin only officially supports the latest stable Neovim version.
If you do not want to update yet, please pin the version of this plugin.
