WireGuard Windows 0.6.1 - Existing tunnels disappeared and ZIP import not working

Hello,

I am reporting two critical issues after updating WireGuard on Windows
(version 0.6.1):

1) Existing tunnels disappeared after update
- All previously configured tunnels are no longer visible
- The Configurations folder appears empty:
  C:\Program Files\WireGuard\Data\Configurations\

2) Cannot import new tunnels (ZIP files)
- ZIP configuration files are not visible in the import dialog
- Even using "*.*" filter, no files are shown
- The files definitely exist in the selected folder

This issue is affecting multiple users in a production environment.

Please confirm whether this is a known issue or a regression in version 0.6.1.

Thank you.
