Installing plugin without preinstalled Leaflet breaks site

[wintermoor]

Installing WP-plugin "Integration between Leaflet Map and CiviCRM" without having WP-Plugin "Leaflet Maps" pre-installed breaks the site (html 500 on my WordPress 5.8)

I could fix it on the database (delete plugin in active_plugins on table wp_options), then install Leaflet Maps first and integration-plugin second. Maybe there is be a better way?
