Failed to open issue

Sounds like anti-virus getting in the way or you’re trying to access an area of the computer you don’t have granted permission to access.

Try adding an exclusion to Windows Defender to ensure Shotcut is not blocked.

Shotcut opens but is "not responding"

The problem could possibly be Windows Defender or some other antivirus program blocking access to the binary files. As a temporary test, I suggest to disable any antivirus programs to see if Shotcut is able to start. Some antivirus programs allow some programs to be excluded. Instructions for Windows Defender are here: https://support.microsoft.com/en-us/windows/add-an-exclusion-to-windows-security-811816c0-4dfd-af4a-47e4-c301afe13b26
