Failed to resolve component: hello-word
If this is a native custom element, make sure to exclude it from component resolution via compilerOptions.isCustomElement.

Any additional comments?

Why global components cannot be resolved

Manually calling render creates a tree that doesn't belong to the current app instance, so it can't resolve components registered under the app's scope.

Then how should I deal with this problem

@LinusBorg

use createApp instead of render and re-register all global components with that new app.
