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...
- Thanks, Joachim. I updated the bug report to note that 26080 is included.

I opened a case at Microsoft as i also suffered from that Bug. Windows Server 2025. NTFS. It was even within VMs when the VM hosted VHDX profiles. No problems with ReFS.
The support engineer confirmed that the combination NTFS, TRIM and the new NVMe Driver for Windows 2025 seams to be responsible for it.
Should be fixed with 2026-08/09 CU.
