Weird error message when using Coq on Vimtex

[ndrew222]

I get this weird error that appears when the pop-up menu is supposed to show up.
I'm not sure what I did, but it shows up a bit irregularly and only after a little bit of use.

I'm running Neovim 0.10.1
Vimtex v2.15
If there is anything else I can add to make this report more helpful, please let me know

So I was using the digestif language server when I made the report, but I just tested it with texlab, and I seem to get the same issue.
