Magento 2.3.7: “Create New Order” page in admin pa…

When attempting to produce an order from the admin panel, I obtain a web page without menus/headers:


I attempted:

php bin/magento cache: tidy
php bin/magento cache: flush

php bin/magento configuration: di: assemble
php bin/magento indexer: reindex

php bin/magento configuration: static-content: release -f

that really did not transform anything, I additionally inspected the logs, however really did not discover anything …

Any kind of assistance is valued, many thanks!
