Error: Unable to create archive directory

Hi all!

Please take a look at the debug log below and help me solve this issue. From the debug log I understand that the plugin is trying to create the archive directory (/app/public/wp-content/plugins/simply-static/static-files/simply-static-1-1627417771/) to store the static files but is unable to create it.

I am running the site on my local development environment (Local by Flywheel).

Thank you for your help!
