I think this will solve ur issue

Yup I have also the same problem first of all do all these steps I think it resolve your issue:-
1. Go to settings of TWRP and reboot recovery.
2. Now format all the internal storage if u have important files in internal storage skip this step
3. After that go to advanced wipe and select system and data one by one and change its format to ext4.
4. Now advanced wipe everything.
5. Thats all now you can install lineage 15.1

I did the same and its working properly in my phone.
This problem occurs due to change of format of data to f2f so convert it to EXT4 and its fine

Normal procedure. Fastboot boot command
Boot to TWRP.
Reboot to TWRP through reboot menu.
Factory reset.
Advanced wipe: change data file format to ext4
Reboot to TWRP through reboot menu again.
Wipe, format data.
Now wipe system, cache and dalvik.
Reboot to TWRP again.
Flash rom.
Gapps.
Magisk if wanted.
Wipe dalvik and cache.
Reboot and enjoy

Bro I already mentioned first of all you have to Factory reset but it will wipe all your data from internal storage so do have a back up for that. Encryption issue can only resolved by factory reset.
