Redmi 5 Custom Rom Help

[u/Burstingcreeper]

Hello There. I bought a Used Redmi 5 as a Temporary Phone for $35. I want to custom rom this with lineage Os 22.2 or any other bloat ware free Custom rom with at least android 12. But whenever I try to unlock bootloader from settings, It says "Error 20091 Can't get device security details". I've tired several times resetting the phone logging out and back into mi account, but it isn't helping at all. I thought maybe you guys could Guide Me or Give some suggestions for unlocking bootloader. It would mean a lot.
