Hi Sophia,
That error means WSL couldn’t properly register Ubuntu because the subsystem or virtualization support isn’t set up correctly. Make sure both “Windows Subsystem for Linux” and “Virtual Machine Platform” are enabled in Windows Features, then reboot. Update to the latest Windows build and install the newest WSL kernel package from Microsoft. Run wsl --set-default-version 2 to ensure you’re on WSL 2, and if Ubuntu was partially installed, remove it with wsl --unregister Ubuntu and reinstall from the Microsoft Store. Also check that the LxssManager service is running and that virtualization is enabled in BIOS. These steps usually clear the 0x80004005 error and let Ubuntu initialize normally.
