Windows app doesn't works

Hi there, the Windows app I found here: https://www.omi.me/pages/download doesn't seem to works.

Windows Defender does find a Trojan:Win32/Bearfoos.A!ml (false positive, I guess/hope), After deactivating WD and installed the app, (i do have the files in program files, see screens shots), and run Omi.exe as an administrator the process launch but nothing appears, no app displayed. Im on Windows 11 Pro for Workstations Insider Preview version Dev, OS build 27913.1000, Windows Feature Experience Pack 1000.26100.154.0

I try and reinstall today, is the same.
Anyone ?
