Hi,

I just tested on a clean install site and could not confirm the problem.

Can you post your site info found via Dashboard -> Tools -> Site Health -> Info -> Copy site info to clipboard?

Thanks.

Hi,

Are you able to create a task by going to Dashboard -> Task Scheduler -> Add New Task?

The error indicates that a screen object somehow does not exist, which it should. I’d suspect a theme/plugin conflict but please first see if it makes any difference when you create a task.
