Entra Connect 2.6.84.0 displays error when trying to configure containers

I installed Entra Connect 2.6.84.0 on a fresh install of Windows Server 2025 and get an error message when trying to configure the containers of the local AD:

(after pressing the button Containers... you need to enter a AD user and password, afterwards the below error message is displayed)

Microsoft support could not help and recommended to use the configuration wizard to filter OUs.

This works for me, but I still wonder if anyone else had this error?
