+- Please double check your setup and check if minium setup works or not
+- It should works for 0.5.1, neovim 0.6.x prefered.
+- Check console output
+- Check `LspInfo` and treesitter status with `checkhealth`
+- Turn on log and attach the log to your issue if possible you can remove any personal/company info in the log
