'Using Lit in Visual Studio Code, ReferenceError: window is not defined

I'm attempting to get lit working in Visual Studio Code but keep running into this error:

ReferenceError: window is not defined
    at file:///C:/Users/C2Ran/Desktop/JobSearch/Epigraph_TicTacToe/node_modules/←[4m@lit←[24m/reactive-element/css-tag.js:6:9
←[90m    at ModuleJob.run (node:internal/modules/esm/module_job:195:25)←[39m
    at async Promise.all (index 0)
←[90m    at async ESMLoader.import (node:internal/modules/esm/loader:337:24)←[39m

←[90m    at async handleMainPromise (node:internal/modules/run_main:61:12)←[39m

The error appears both when running node ./app.js from git bash, and when running the debugger in VS Code. I'm also using the exact code from https://lit.dev/playground/ (the JS versions, not TS versions). I created my project folder and used node.js to install lit inside it with npm i lit as instructed on their website, then created my html and js files using VS Code. For completion's sake here is my html:

<!DOCTYPE html>
<head>
  <script type="module" src="./app.js"></script>
</head>
<body>
  <simple-greeting name="World"></simple-greeting>
</body>

Here is my js:

import {html, css, LitElement} from 'lit';

export class SimpleGreeting extends LitElement {
  static styles = css`p { color: blue }`;

  static properties = {
    name: {type: String},
  };

  constructor() {
    super();
    this.name = 'Somebody';
  }

  render() {
    return html`<p>Hello, ${this.name}!</p>`;
  }
}
customElements.define('simple-greeting', SimpleGreeting);

Here is where window is referenced in the lit directory (where the error is):

import{getCompatibleStyle as t,adoptStyles as i}from"./css-tag.js";export{CSSResult,adoptStyles,css,getCompatibleStyle,supportsAdoptingStyleSheets,unsafeCSS}from"./css-tag.js";

//# sourceMappingURL=reactive-element.js.map

the window variable is defined in C:\Users\C2Ran\.vscode\extensions\ms-vscode.vscode-typescript-next-4.7.20220311\node_modules\typescript\lib\lib.dom.d.ts as follows:

declare var window: Window & typeof globalThis;

for some reason css-tag.js isn't able to grab this definition (despite the fact that I can right-click 'window' in css-tag.js itself and click 'Go to definition', leading me there).

Does anyone know a good workaround for this?
