Windows 11 Sandbox needs a community workaround to function — why is this still happening?

Windows 11 Sandbox hit by error 0x800705B4, making it unusable – Users are still waiting for an official fix.

Windows 11’s built‑in Sandbox feature has been hit by a widespread bug that makes it completely unusable for many users. Reports show the tool stalls at launch for nearly ten minutes before failing with error 0x800705b4, even after reinstalling the feature or running SFC/DISM scans. Multiple Windows 11 builds appear affected, and users across Microsoft Q&A, GitHub, and forums say they’ve been waiting weeks for an official fix.

On Windows 11, the Windows Sandbox features have been broken for some time. However, this issue is flying under the radar because Microsoft has yet to acknowledge it or provide answers to affected users.
