SQL Error on config page right after installation

[OvalMedia]

Preconditions

1. Magento 2.4.4
2. MariaDB 10.6.15
3. database name is 'www.my-shop.com'
4. Mailchimp module v103.4.57
5. Shop is a copy of a live system in a local environment
6. Shop is in developer mode

Steps to reproduce

1. install module via composer: require mailchimp/mc-magento2
2. enable module: bin/magento module:enable Ebizmarts_MailChimp
3. run setup: bin/magento setup:upgrade
4. compile: bin/magento setup:di:compile
5. in backend go to mailchimp settings page

Expected result

no errors

Actual result

Page opens with an error message on top: "A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later."

In the system.log I find this message:

main.ERROR: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'www.my-shop' doesn't exist, query was: SELECT `main_table`.`mailchimp_store_id` FROM `mailchimp_sync_ecommerce` AS `main_table`
 LEFT JOIN `www`.`my-shop` AS `core_config` ON value = mailchimp_store_id WHERE (value is null) GROUP BY `mailchimp_store_id` [] []

Apart from this the configuration seems to work fine.

Additional information

My suspicion is that the system chokes on the database name, as it contains dots ("www.my-shop.com").

Edit

I just mirrored the same system onto a staging server where the database name differs (no dots). It confirms my suspicion, no sql error occured.
