Just an update. The question was closed with links to some previous post. I have tried those already and they don't work anymore. Both the post use "expandRootElement" method to expand the nested root element. That's the one I ma using and is not working. Any help is appreciated.
My web application contains nested shadow root elements something like this (Sorry I can't share my original code)
Here is my code that I was using to work with the element (Download button in this case)
public WebElement expandRootElement(WebElement element) {
WebElement ele = (WebElement) ((JavascriptExecutor)driver)
.executeScript("return arguments[0].shadowRoot", element);
return ele;
}
It was working fine till yesterday using Chrome 95 on Selenium 3.14. Today I upgraded to Chrome 96, updated the chromedriver to match that and Selenium to 4.0.0. The same code is now not working with this error
java.lang.ClassCastException: class org.openqa.selenium.remote.ShadowRoot cannot be cast to class org.openqa.selenium.WebElement (org.openqa.selenium.remote.ShadowRoot and org.openqa.selenium.WebElement are in unnamed module of loader 'app')

I tried the same with FireFox too (version 94) and get this error
