Steps to Reproduce:

1. Create an abstract class with an abstract async method ( returns a Promise)
2. Create another class that extends this abstract class, and try to write the method using autocomplete, by starting with typing async
3. See that it gets autocompleted incorrectly

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.86.0. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

Still happening on 1.86.0, with Typescript Nightly extension version v5.4.20240204.

Copiable code:

abstract class AFoo {
    abstract bar(): Promise<void>;
}

class Foo extends AFoo {
    async b
}

Here is the completion entry:

        {
            "name": "bar",
            "kind": "method",
            "kindModifiers": "abstract",
            "sortText": "11",
            "insertText": "async bar(): Promise<void> {\n    $0\n}",
            "filterText": "bar",
            "isSnippet": true
        },

No replacement range is returned
