ReFS volume appears RAW (version doesn't match expected value) after Windows Update

I solved this by uninstalling KB5009557. The ReFS volume came back working as it should, instead of appearing as RAW.
Update: since even the February 2022 Windows Update bricks ReFS in the same way, and hints from Microsoft are that ReFS 1.x is no longer supported, we copied everything to new disks, upgrading ReFS from 1.2 to 3.4 in the process. Such a (manual) ReFS upgrade should be the solution that everyone needs, allowing to re-enable Windows Update.

Thanks for clarification Stephen!
One question aside if a customer uses WinPE or WinRE from Win10/2016/2019/2022 is this one able to read ReFS natively, I am aware it is not for Storage Spaces.
Some still use Windows Backup to backup files this be restored? TY.
