Web automation, problem with writing text to field due to invalid object reference

I have a web automation flow where I cannot write to a specific UI element, with an error message stating that the object reference is not valid.

I assume this is because of the actual web address is dynamic, even though the element ID in the DOM is still identical.

Within my flow a button is clicked on the starting web page, which launches another tab in the browser. It is on this new tab that my problematic UI element is located on. Is there any way to make the subsequent web automation steps interact with this new tab automatically?

Or, what ways are there to make the web address dynamic within the Desktop flow, e.g. just looking for part of the URL?

Thanks.

You just have to set/attach the browser instance to the new tab e.g. through title or URL

Allright.
That was actually the first thing I thought about, but I could not see any way that I could set it to the new tab.
How would you go about doing that?

After that button click you need to add the launch web browser action and set the launch mode to an existing instance with details about the new tab (title or URL): https://docs.microsoft.com/en-us/power-automate/desktop-flows/automation-web#building-a-web-automation-flow
