WSL not working after windows update

### Windows Version

10.0.26200.7462

### WSL Version

2.6.3.0

### Are you using WSL 1 or WSL 2?

- [x] WSL 2
- [ ] WSL 1

### Kernel Version

6.6.87.2-1

### Distro Version

Ubuntu 22.04.5 LTS

### Other Software

Windows

### Repro Steps

Get a forced update from Windows, which will restart your computer forcely.
Then try to run Ubuntu or VSCode connected to it... and get errors.
Now imagine if you lost all the work and setup and temporary files not sync with github.

### Expected Behavior

Everything just works and using WSL feels safe to work with.

### Actual Behavior

Fear of losing progress. System not working. Losing time to report bugs and blocked from work while not finding a solution.

### Diagnostic Logs

Fehler beim Anfügen des Datenträgers "C:\Program Files\WSL\system.vhd" an WSL2: Das System kann die angegebene Datei nicht finden.
Fehlercode: Wsl/Service/CreateInstance/CreateVm/MountDisk/HCS/ERROR_FILE_NOT_FOUND

No repository file, test, or code entry point is identified. Start by reproducing WSL 2 startup with the listed Windows, WSL, kernel, and Ubuntu versions, then investigate the system.vhd mount error and compare behavior after the forced update. Done means identifying a reproducible cause and a validated recovery or fix.
