Just upgraded Shotcut and made a project but kept getting “Failed”. Rebooted PC but still the same.
Checked memory > OK checked files were OK with virus scanner.
Rebooted and re-installed 22.01.30 and now it’s working!
Thank you for sharing and giving people hope that it can be made to work. I still believe that antivirus programs are getting in the way somehow. But I do not have definitive proof.
If I had the same problem, I would probably choose to turn off the VPN and temporarily turn off my antivirus and firewall. Because sometimes some niche software doesn’t recognize Shotcut as safe, it can be a little problematic to install, and I’ve encountered a similar situation when installing other software.
