Start by reproducing the failure with the `lua-language-server` command and inspect the loading of `/home/chiller/.luarocks/lib/lua/5.4/lpeglabel.so`. Trace the `lpeglabel` require path through `glob/glob.lua`, `glob/init.lua`, and the subsequent startup stack. Done means the module loads without the `lua_gettop` symbol error and the language server starts normally.
