Hi Homeeey,
Thank you for reaching out to Microsoft Community.
Please check on Task Manager first if there are other application that are running using the Camera of the device. If you have any apps using the camera, please select it then click End Task.
Please run these steps on your Surface Pro 7 then see if the issue persist:
1: Reset Camera app
Go to Windows Settings > Apps & Features
Locate and click
Camera
Select Advanced options
Locate and click
Reset
Restart the Surface
2: Check Privacy Settings
Go to Windows Settings >
Privacy
Select Camera
Make sure that the
Let apps use my camera option is On
3: Run Surface Diagnostic Toolkit and check Windows Update
4: Update drivers and firmware
Check what is the current OS Build of your Windows version by going to
Settings > System > About.
Go to Download driver and firmware for Surface, choose Surface Pro 7 then click
Download on the next page.
Choose the .msi file that matches your current OS Build and click
Next.
After downloading, run and install the .msi then Restart.
5: Run System File Checker Tool in Windows 10
If still the issue persist, other cause of this issue will be malicious cyber infection like Trojan, Worm or adware. I suggest that you proceed in re-installing windows on the device using a USB Recovery Image. This option will reimage the entire device
and reload Windows including the drivers and firmware. It is the most complete form of Reset and it will wipe out everything on the device so you might need to back up your files first. You will need also a 16GB/32GB of flash drive that must be formatted into
FAT32 prior to downloading the Recovery Image. If you like to try, you can follow the steps provided below:
How to Download, Create and Use a USB recovery drive
To download the Recovery Image:
- You'll need a PC running Windows 7 or later or Surface Device.
- Visit the page to Download the recovery image for your Surface
- Sign in with your Microsoft Account
- From the list of Surface devices available, select the device that you need a recovery image for
Please note that while you will only be presented with devices that are currently registered on your account, you will also be presented with the option to get an image for a different type of device. If you try to use this option, you will be prompted to enter
the serial number for that device
4. Download the recovery image using the button on the page
5. When the download bar pops up at the bottom of your screen, save the file in a location you will be able to find it.
Format USB Drive:
- Note: Formatting a recovery drive will erase anything that is already stored on your USB drive. Make sure to transfer any important data from your USB drive to another storage device before using it to create a Surface
USB recovery drive.
- Insert your USB drive into the USB port of your PC.

- Tap or click OK when the format is complete
Create a recovery drive:
