I told nvim-treesitter in its config file to install this parser, and I got this error:

In case that is relevant, I'm on Windows 10 (sadly) and using Neovide. I'd love help. Thanks!

I think you may have more success if you raise this issue in the nvim-treesitter repo. This repo is for the underlying grammar used for the Python parser (and it doesn't seem like the code being compiled in your snippet comes from this repo -- at least I am unable to find any references to isa<X> in this codebase).

[mikwee]

Alright, thanks. I'll try, and it seems like they just woke up and started answering issues, Just at the right time
