Please be so kind as to read my full post before responding.
Thank you for consideration.
In my last editing session, I came across a new error.
I am just posting screenshots and the error message for further review by someone responsible.
My focus was not in the browser containing the PowerApps Studio tab for a while.
When I switched back from a different program, the error message was there.
I was not doing actually doing anything in PowerApps studio to initiate the error, at least as far as I know.
WebAuthoring abnormal termination.
