There were some errors with the script and so it was going to clean up and as there was nothing to unmount it was showing that error.
I’ve updated the script and it works for me with Xperia 10 II on 4.5.0.
The changes are to accomodate for:
Android version 11
One of the gapps zips is now appended with arm64
The product directory under system now appears to be a link and can’t be copied to.
