Stuck after google login and authorization

[007SuperMario]

Hello,
i'm trying Mountain Duck with google drive, but after the google login and authorizing access, the program gets stuck forever with the message I paste.

EDIT:
I also tried to authenticate by setting OPERA as the default browser instead of Chrome, but the behavior is identical.

From your description this would indicate we are unable to register a protocol handler that handles the redirect from the web browser after login. Please open a Windows PowerShell prompt and enter

Get-Item HKCU:\Software\Classes\com.googleusercontent.apps.996125414232-nk3icebd7k519k2bla2vsc9h50hfrgdk\shell\open\command\

Please verify that you can run Mountain Duck from the "Run"-dialog:

• C:\Program Files\WindowsApps\io.mountainduck_5.0.1.27950_x64__nx15cxr8682sp\Mountain Duck.exe
  or alternatively from the Command Line:
• "C:\Program Files\WindowsApps\io.mountainduck_5.0.1.27950_x64__nx15cxr8682sp\Mountain Duck.exe"

Additionally, please open up the Developer Console in Chrome, then perform the authorization, and send us - in the internal support tracker - the log output.

Same problem here
Run, doesn't work, CMD does nothing, when i opened directory and tried to launch using icon i got this error

English Translation:
"Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

After changing the ownership of the directory and granting full control to the CurrentUser in the security properties, the login began to work.
