The issue was ReSharper. I disabled the plugin and it worked fine. For reference I have attached two picutres, the first with ReSharper enabled, and the second with it disabled.
问题是 ReSharper。我禁用了插件，它工作正常。作为参考，我附上了两张图片，第一张启用了 ReSharper，第二张禁用了它。

With your given tsconfig.json it compiles fine:
使用您给定的 tsconfig.json，它可以正常编译：
let button = <HTMLElement>document.body.querySelector(".btn");
button.addEventListener("click", () => { });
Your IDE is lying. Works fine in VSCode / alm
你的 IDE 在说谎。在 VSCode / alm 中工作正常
