Got 5 VMs damaged, can no longer boot them

Hello,
Yesterday I updated Parallels Desktop 12 for Mac to version 12.1.3 (41532) from version 12.1.1 (which I last ran in November 2016).
I run a 16 GB iMac mid 2011 under macOS Sierra 10.12.3 (16D32). My volume is a v4,7 TB FusionDrive (750 GB SSD + 4 TB HD), and it is in a perfect shape, regularly checking with Disk Utility, and reporting no error.
I have 5 VMs that I use for testing with different Windows versions : 1 Windows XP, 1 Windows 7, 1 Windows 8.1, 2 Windows 10.
Yesterday, after updating to Parallels Desktop 12 for Mac to version 12.1.3, I launched each VM to update to latest Parallels Tools.
Install of Parallels Tools was fine on all VMs, and I also applied latest Windows updates on each VM. Everything was working fine, each VM was booting smoothly.
I then compressed each VMs to regain a few GB.
Later in the day, when relaunching Parallels all VMs can't boot. They are all corrupted, and I can't repair them.

 

Try running Windows into safe mode and then reboot Windows:
As per the screenshot, select Advanced options -> Troubleshoot -> Startup settings -> Restart -> Safe mode with networking select the corresponding number.
Then, try rebooting Windows virtual machine.

 

It didn't work. I tried on the 4 VMs.
