Hi. I'm David, and I'm happy to help you.
To be able to assist you better, please clarify the following:
- Are you using Windows 10 or Windows 11?
- Where exactly are you seeing the "unable to open" message? Does it appear right after turning on the laptop (before reaching the desktop), on the sign-in screen, or when you try to open a specific app/file?
- Is there an error code or any additional text shown along with that message? If you can take a photo of the screen with your phone and attach it here, that would be very helpful.
- What is the manufacturer and model of your laptop?
Looking forward to your reply.
