https://community.blueprism.com/t5/Product-Forum/A-new-guard-page-for-the-stack-cannot-be-created/m-p/69006#M21611 When trying to use AA mode for a text box on a webpage I have seen this error show up (Automate.exe - System Error - A new guard page for the stack cannot be created). This then causes BP to crash. I am not sure why this is happening or what could be done to resolve.  Basically the text field is one where the HTML write stage wont work as the site doesn't register that something has been written so I am wanting to use AA mode to use Send Keys.  I am able to spy the element but if I try to use Highlight in the App Modeller or use the element in a navigate action BP just crashes. Has anyone had this before and/or know of any solutions?
