Changing languages doesn't seem to restart LSP

[ReKylee]

My default language is set to Python, but when I use :Leet lang to change to CPP, my LSP, linter and formatter stay on Python.

I've tried opening python and cpp files by themselves and it seems like it works standalone, just not when changing through the command. I've also tried opening a python file, and then switching to a cpp file, and that works too(probably because it opens in a new buffer?)

:Leet lang also opens a new buffer. Could you switch between Python and C++, then paste your LspInfo?

And your neovim version

Sure :D

By this, you mean that you are getting python auto completion on a c++ file?

[ReKylee]

Well actually, it just doesn't do anything and the python linter seems to display python errors on the cpp code

EDIT: Looks like the linter is also dormant, as the warnings remain even if I delete the entire code haha.

[kawre]

How does it behave when you set lang to cpp, then switch to python with :Leet lang?

[ReKylee]

Switching from CPP to Python3 works well, and pyright starts up and I get correct linting, but then switching back to CPP keeps the Python linting for some reason?

Could you add commit = "94c16d8be8d09c0b543782b0323ce6eb1fbc95c5" to leetcode.nvim config? Does it change anything?

[ReKylee]

With commit = "94c16d8be8d09c0b543782b0323ce6eb1fbc95c5" added, it seems like the previous lint is "stuck"? But the CPP lint and autocomplete work
