VB Startup after Host Shutdown without VB Guest Shutdown

[Pigo]

VirtualBox doesn't show up after a host shutdown (Start/Shutdown) without VB guest shutdown (VB was running and killed by windows shutdown)

The Windows 11 VM was perfectly running prior to this accidently caused shutdown.

Host:

Windows 10 Enterprise / 21H2 / 19044.1826
AMD Ryzen 9 3950X 16-Core Processor
RAM 64,0 GB

Guest:

Winwows 11 Professional / latest updates (yesterday)

VB Processes running:

VBoxSDS.exe: ~ 1.8 MB

VBoxSVC.exe: continously increasing -> >100GB

VirtualBox.exe: 6.6 MB

In task manager one can see continuously increasing memory consumption of VBoxSVC.exe which results in a host crash (in my case at over 100GB (64GB RAM installed)
