Can not unlock laptops after meeting, when laptop is offline then it works.

Users can sometimes not unlock laptop after break.

Since a few weeks we have this ugly problem in our company domain. Users who went in a meeting or go for lunch can sometimes not unlock their laptops when they come back. Windows often says "Password incorrect" or "your password have been changed on an other device" but the password is not wrong.

There are users they had this issue a few times in the last weeks, other users never had it since we know about this issue.
People work in the same team with the same group policies there are no differences but some people in the team have it, other never had it.

When we plug out the network cable and also Wi-Fi on these computers the users then can log in, then the stored credentials are used.
We already checked the power settings so that the laptop does not shutdown the network adapters but that does not fix the problem. 
Domain controllers are always reachable there are no replication errors, or network timeouts.

We use Windows 11 25H2 in our company network.
