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...

Hi, Joachim. Sorry you are feeling frustrated about this -- we do have a lot of different demands on our time in any given day; we are as human as you are. I work in engineering, not marketing. I'm trying to see if the de-dup team has enough data to diagnose this, given the feedback you've provided.

Thanks,
Michael Bernstein (MSFT)

If you want to look how it plays out with Server 2022 and nVext: I recorded a video which is on my home page https://www.joumxyzptlk.de/tmp/microsoft/S2022-Nested_Deduplication_VDI-Hyperv_profile_kills_filesystem_v2.mp4
Video was created on AMD Ryzen 5950 with Win11 as host, but is the same on Dual Xeon 6226R with Server 2019 (HP ProLiant DL380) as host.

  Thanks, Joachim! I attached that video to the bug report to provide additional context for the engineering team.

    Could the engineering reproduce this bug, maybe even as easy as I can? I don't expect a fix so fast, but if they could reproduce it would be a good feedback.

Thank you for your reply! The problematic part is actually it applies to Server 2022 too. I can reproduce it with both.
