Here the SQL :

SELECT * FROM `key_value` WHERE `collection` LIKE '%upgrade_status_scan_results%' ORDER BY `key_value`.`name` ASC

But theres is no line for group. It seems, it did not create any entry in the key_value table for the module group.

In the backoffice, the module is marked as compatible

Before scan

If trying to scan it from the backoffice
We also have a timeout.
But a problem have appear :
after scan

Probleme

Do you have any idea ?

While I understand the timeout on this scanning result is not good I think its an underlying problem in how phpstan interacts with something in group's code. On the other hand, given that both branches highlighted of the project are Drupal 10 compatible, I don't know what else would you do with any scanning result? I would take the info that it is compatible and sleep well for this upgrade? :)
