Vimtex only works sporadically when installed with Lazy

[neilzxu]

Description

Whenever I open a .tex file in neovim, I get the following error with some probability.

(Note that I am running with lazy = false in the Lazy.nvim config)

Steps to reproduce

1. Open a tex file (even new/blank one with ending .tex).

Expected behavior

The file opens and vimtex runs.

Actual behavior

I get the following error some of the time

Error detected while processing BufReadPost Autocommands for "*":

Do you use a latexmkrc file?

Yes

VimtexInfo

I can't run VimtexInfo, it says `Not an editor command`

You say it sporadically works, but then you say

I can't run VimtexInfo, it says Not an editor command

Well, can you run :VimtexInfo and show the output when it works?

VimTeX works well for me and most other people, so I am quite sure the problem is on your side. But I need much more information to be able to help you here. I don't know anything about your system or configuration. :VimtexInfo will tell me some of these details, but I also need to see your config.

Fixed by setting priority = 100 i.e., higher than default, in the vimtex config settings
