Research direction
No source file or test is named in the report. Start by reproducing the pre-mounted configuration with an encrypted root, verifying the root mount at /mnt and EFI mount at /mnt/booti, then trace the validation entry point that reports the missing root. Done means archinstall recognizes the mounted root and proceeds without the invalid-configuration error.

describe the problem
While installing Arch Linux using archinstall with an encrypted (LUKS) root partition(pre- mounted configuration), the installer showing the error:
"Invalid configuration: root partition not found"
This happens even though the root partition is correctly opened, formatted, and mounted at /mnt, and the EFI partition is mounted at /mnt/booti.
Manual verification confirms that the root filesystem is present and accessible, but archinstall fails to detect it.
Please let me know if there is any solution to this problem. I am unable to use my PC due to this.
