[BUG] GUI doesn't appear during "Select the Windows 10 Edition to Optimize"

[Username-Is-Unavailabl]

Bug description
After I launch Start-Optimize.ps1 in (Administrator) PowerShell, with the following command: "powershell -ep bypass -file C:\Users[My Username\Downloads\Optimize-Offline-4.0.1.7\Start-Optimize.ps1", the script copies the .esd file, then at the top of the window it says "Select the Windows 10 Edition to Optimize", but no GUI appears.

• Image Name: Windows.iso

• Host Environment: Windows 10 Pro

I encounter the same problem with the 40.0.1.8, have you found a solution ?
