Issue With S3FS

Problem/Motivation

When installing this theme, the settings as well as non-admin pages had an error pertaining to S3FS. I uninstalled the module and DXPR worked. Installed S3FS again and got this message:

Drupal\Core\File\Exception\FileWriteException: The specified file 'temporary://fileGsjPq1' could not be moved to 'public://dxpr_theme/css/themesettings-dxpr_theme_STARTERKIT.css'. in Drupal\s3fs\S3fsFileService->move() (line 302 of modules/contrib/s3fs/src/S3fsFileService.php).
