Phone: Samsung S9 Plus, 256Gb
OS: Lineage OS 17.1 (Android 10)
ROOT: TWRP 3.5
I installed Lineage OS 17.1 on a Samsung S9+. It's been working fine so far. However, when I encrypt the OS from the security menu, right after the screen goes black with the green android-like logo, the phone quickly reboots back to the non encrypted OS. Going again through the process does not help.
logcat shows:

--------- beginning of crash
I tried the steps given here on /data (/dev/block/sda25), but it did not do it for me either.
- Any idea on how I can debug further
Cryptfs : Unexpected value for crypto key location? - Is there a way to encrypt /data via the command line if this keeps failing?
