Finding objects fails after downloading

In my testcase, i test an export to xml function that creates a download.
After the successful download, the chrome browser download bar opens and every action afterwards fails because the elements are not visible to Katalon. It doesn’t matter which testobject, so it doesn’t seem to be a failure of the xpaths.

Error Message:

Test Cases/Repo Trading Received Tab FAILED because (of) Unable to click on object ‘Object Repository/Repo Trading View/a_content-header-icons refSett’ (Root cause: org.openqa.selenium.ElementNotVisibleException: element not visible
