It can be caused by a variety of factors, but it usually indicates a problem with the Visual C++ redistributable packages or a corrupted system file. Here are some steps you can try to fix the error:

1. Repair or reinstall Visual C++ redistributable packages: Go to "Control Panel" > "Programs and Features", and locate the "Microsoft Visual C++ Redistributable" packages installed on your system. Select each package one by one and click on "Repair" or "Uninstall/Change" and then "Repair". If the repair option is not available, try uninstalling the package and then reinstalling it from Microsoft's website.
2. Check for system file corruption: Run the System File Checker (SFC) tool to check for and repair corrupted system files. Open a Command Prompt window with administrator privileges and run the command "sfc /scannow". This will scan your system for any corrupted files and attempt to repair them.
3. Check for Windows Updates: Make sure your Windows 10 operating system is up to date. Go to "Settings" > "Update & Security" > "Windows Update" and click on "Check for updates". Install any available updates.
4. Disable antivirus software: Sometimes antivirus software can interfere with the build process. Try disabling your antivirus software temporarily and see if that resolves the issue.
5. Reinstall Visual Studio: If none of the above steps work, try uninstalling and then reinstalling Visual Studio.
