Additional information about the issue

Export in three:0.153.0 and in @types/three:0.153.0 are defined as

    "exports": {
        //...
        "./addons/*": "./examples/jsm/*",
        //...
    }

which should allow to import anything from ./examples/jsm/

[matheusschreiber]

Add .js in the module import.

- import type { GLTF } from "three/examples/jsm/loaders/GLTFLoader"
+ import type { GLTF } from "three/examples/jsm/loaders/GLTFLoader.js"
