rootUri is incorrect in VS Code extension

[JayRPlayz]

Whenever i open a specific workspace, that i have currently saved, it lags my pc for a solid few minutes, making it completely usable during that time. Disableling the lua extension (by summeko) seems to fix the issue. it also sais that its scanning "" and

that its trying to load several thousand files. how do i fix this?

not enough information 😕

suggest you to read: https://luals.github.io/wiki/faq/#how-can-i-improve-startup-speeds

TL;DR: Only include necessary libraries and ignore as many files/directories as you can.

The most effective (and obvious) way to improve startup times is to load fewer files. The startup time of the server is proportional to the total size of all Lua files in your workspace. Try excluding unnecessary directories and files using workspace.ignoreDir.

LuaLS will always scan all files in your workspace, because it has to preload all possible lua files to make type inferencing works.
To prevent LuaLS scanning undesired folders, you can create a .luarc.json config file and play around with the workspace.ignoreDir setting mentioned above:

{
    "$schema": "https://raw.githubusercontent.com/sumneko/vscode-lua/master/setting/schema.json",

    "workspace.ignoreDir": [
        "i_dont_want_this_folder",
        "i_want_this_folder/but_not_this_sub_folder"
    ]
}
