Samsung stuck at boot Lineage OS boot animation after flashing GSI

My device is Samsung Galaxy A9 2018 (SM-A920F), A/B and TWRP unsupported. Therefore, I combined system.img (Andy Yan’s Lineage OS 18.1 A/B), vendor.img and boot.img (both are stock) into a single .tar file and flashed it via Odin. It booted and said “encryption was unsuccessful” and asked for factory reset. I did it, it rebooted and stuck at Lineage booting animation.
Does anyone know how to resolve it?
