26063 deduplication data corruption is still there.
From Server 2022 up to this newest 26063 build, they all have the same problem, as described here: https://techcommunity.microsoft.com/t5/windows-server-insiders/server-vnext-26040-and-server-2022-de...

Al little update on this: I am in contact with others to reproduce this, and we came across the "write cache "setting of the drive. But even with the checkmar removed it still happens. We are trying to narrow it down, for example minimum CPU GHz speed and similar things. Sadly I cannot do such a test in the Xeon 6226R on bare metal instead of nested-V, that other machine is not mine.
