URGENT - Windows 11.pvm corrupted after iCloud sync - 47.4 GB VM containing professional data

Hello,

I urgently need help from a Parallels engineer.

My Windows 11 virtual machine was working perfectly on July 31, 2026.

The next day it suddenly stopped working.

Environment:

• macOS 26.5.2
• Parallels Desktop 26.4.0 (57513)
• Apple Silicon Mac

The .pvm package is still visible in iCloud Drive and still shows a size of 47.4 GB.

However, Parallels now reports:

- PRL_ERR_DISK_XML_MISSING
- DiskDescriptor.xml missing
- Failed to open disk image

The virtual hard disk (harddisk.hdd) now appears empty and cannot be opened.

This virtual machine contains several years of professional work, including:

- Quadra accounting software
- Microsoft Money banking data
- Professional documents

Yesterday everything was working correctly.

Today it is impossible to boot the VM.

Could someone from the Parallels engineering team please advise me before I perform any action that could permanently damage the virtual machine?

I can provide:
- Parallels logs
- Terminal output
- Screenshots
- Any additional information required.

Thank you very much.
