Describe the issue below.

The command ./backup.sh stops at the line

adb: error: failed to stat remote object '/data/preloads/apps-postinstall/GoogleHandWritingIME/GoogleHandWritingIME.apk': Permission denied

just listed all apps an indeed this is the only one

Nokia/linux-android-backup-master> adb shell pm list packages -3 -f | grep apps-postinstall
package:/data/preloads/apps-postinstall/GoogleHandWritingIME/GoogleHandWritingIME.apk=com.google.android.apps.handwriting.ime

will try to add an exception for this postinstall in the list

Here a first workaround ... guess: tar would also work with this method, but due to the visible error I've choosen the adb method

Simple workaround

I'll consider adding this workaround.
