I had to uninstall the conda package because it was constantly disconnecting and reconnecting to the kernel and every time it’d do that Emacs would freeze for a couple of seconds. Probably happened about 10 times a minute before I finally deleted the package.

I can’t speak for C but I know Python has a similar thing in PEP8, to add comments at the top of a file. So lsp will show that as an error/warning.
