KSC Admin Server doesn't start anymore since update to Windows Server 2025

[0xDEADC0DE]

We don't know why but our server automatically installed the Windows Server 2025 update.
Since 3 days KSC Admin Server doesn't start. I can start it but it stops after a few seconds.
I don't see anything in the Windows Event Logs. I've tried to do a full reinstallation and a repair installation and
it still doesn't start. Is it just my installation or a known problem with Server 2025?
Are there any other logs I can check?

Hello,

At the moment, Windows Server 2025 is not supported.

The same thing always happens when a new operating system comes out, it takes a while to adapt the product.

Probably will be in a few days, or weeks.

Please open a support ticket in Kaspersky Company Account.

I had no time to take the logs. I've rolled back to 2022 with a backup and everything is working again.
