The same problem happens to me. I'm also on windows, and I have a strong suspicion, that that's causing the problem. Can anyone write an answer, that doesn't use WSL? I tried updating pip, npm and node, and reinstalling all of the servers (emmet_lsp, clangd, pyright) none of them worked. I tried the kickstarter config, and everything worked in there, except for the Lsp. I'm truly lost.
