Additionally, you're currently using a Windows Insider version. This version is intended for testing and is not very stable, so it's not surprising that various issues are occurring. If you want a more stable experience, consider leaving the Windows Insider program:

Hello, Lewi Kristianto

Using the Windows installation package for an overwrite is quite an aggressive solution. If you're still encountering errors afterward, it likely indicates that your current system is severely corrupted, and an overwrite may not resolve the issue. The only option left is a more drastic measure: reinstalling the operating system from a USB drive, without keeping any files. I understand you might be reluctant, but unfortunately, there are no other alternatives. Just remember to back up any important files beforehand.

Hello, Lewi Kristianto

Welcome to Microsoft Community.

The error code 0x800f0920 typically indicates an issue with the Windows Update components. This error may arise due to incomplete system updates or corruption of certain components. The Windows Sandbox is also considered a component of the operating system. Have you tried implementing any of the suggestions related to Windows Update?

Troubleshoot problems updating Windows - Microsoft Support

It is crucial to ensure that all updates for Windows are installed, including those not necessarily used by the Sandbox, such as .NET Framework and Visual C++.

If the Sandbox still does not open, it is advisable to use a Windows installation package that includes the latest updates to overwrite the existing system. This process should not affect the files saved on your computer, but it is still recommended to back up important files beforehand, just in case:
