Hm I’m having trouble to backup the data partition:
Backing up Data (excl. storage)…
Backups of Data do not include any files in internal storage such as pictures and downloads.
createTarFork() process ended with ERROR: 255
Backup failed. Cleaning Backup Folder.
The recovery.log file contains the following at the end:

A huge Thank you! to everybody having made this available.
It’s so good to have this on the phone. And it even can decrypt Android 9 encryption (which is not a given and not required to work).
Thanks I’ve given it a shot. Still the same problem. My guess from looking into the /data/misc_ce folder is that it’s not properly decrypting the second user:
Since this is an A/B device, there is no separate recovery partition.
Recovery is part of the boot.img.
I have linked to a full stock dump above. (Which could be used with fastboot to get back to stock state)
You can also backup your boot.img using TWRP.
That’s what the installer is for, it would replace the recovery in the boot.img.
I don’t think anyone has tested that yet.
Well you need to enter a PIN/password for the work profile when you setup one. I’ve used the same as for the screen unlock for convenience reasons. TWRP does not seem to be able to decrypt with the correct PIN/password though.
