Insufficient storage space: Boot Camp Assistant requires a certain amount of free storage space to create a new partition for Windows. If your Mac does not have enough free space, Boot Camp Assistant may fail.

Corrupted Windows 10 installation media: If the Windows installation media that you are using is corrupted or damaged, Boot Camp Assistant may fail to install Windows.

Security software: Some security software or firewall settings on your Mac may interfere with the Boot Camp Assistant installation process, causing it to fail.

Outdated firmware: If your Mac’s firmware is outdated, Boot Camp Assistant may fail to install Windows.

Incompatible hardware: In some cases, certain hardware components on your Mac may be incompatible with Windows, causing Boot Camp Assistant to fail.

Now, enter the login password to grant the permission. After that, click on the "Turn Off FileVault" button to disable FileVault on Mac.
