Javascript does not execute when I add the IsBrowserInitializedChanged event

Question

my javascript code is not running when I post the event: IsBrowserInitializedChanged. However, if I remove the event, the code will work, but the error will occur later.

Code:

 chromeBrowser.IsBrowserInitializedChanged += (sender, args) =>
            {
                if (chromeBrowser.IsBrowserInitialized)
                {
                    chromeBrowser.ExecuteScriptAsync(codejavascript);
                }
            };
