Heap Corruption after using CfUpdatePlaceholder

I can reliably crash .NET and C++ packaged applications (MSIX) on Windows 11 24H2 with Heap Corruptions, when updating Cloud Filter mini-driver placeholder files using CfUpdatePlaceholder.

Repro: https://github.com/iterate-ch/CloudFiles-HeapCorrupt The application will never actually complete the 300 placeholder updates, and sometime crash with heap corruption inside the loop:

Ausnahmefehler bei 0x00007FFA2DE9DA95 (ntdll.dll) in SyncApp.exe: 0xC0000374: Ein Heap wurde beschädigt (Parameter: 0x00007FFA2DFCB0E0)

This does not happen on Windows 11 23H2.

Please let me know, what I have to do to get this fixed.
