Did you get this resolved?

It appears this doesn't have the proper reference. By chance are you calling it from within an event handler? If so, the challenge is that this within the handler (such as clicking a button) is tied to the thing that triggered the event... in this case a button. You want to bind the event handler function to the web part itself.
Assuming you have something like:
<button onClick="this._buttonClickHandler"></button>
You can fix that by changing your function declaration:
private _buttonClickHandler = (): void => {
this.render();
}
