Could not save marker XML file

Hi since the latest update (6.0.27) I’m getting this:
_

Warning: DOMDocument::save(/homepages/45/d391275139/htdocs/bristoltherapist-wp/wp-content/uploads/wp-google-maps/1markers.xml) [domdocument.save]: failed to open stream: No such file or directory in /homepages/45/d391275139/htdocs/ensohealingrooms.com/wp-content/plugins/wp-google-maps/wpGoogleMaps.php on line 1842
Could not save XML file

Could not save marker XML file (/homepages/45/d391275139/htdocs/bristoltherapist-wp/wp-content/uploads/wp-google-maps/1markers.xml) for Map ID 1

(see: https://ensohealingrooms.com/enso_healing_rooms_directions/)

Changed permissions of wp-content/uploads/wp-google-maps to 777 as requested but nothing changed.

Any suggestions? Would like to continue using this plugin if possible.

Thanks
