You can downgrade via Dev Patched LGUP with locked bootloader.
You can't unlock bootloader on Pie, you have to downgrade to early Oreo firmware with fastboot flash commands.

Unlocked bootloader is not necessary to downgrade. In fact you have to downgrade to unlock bootloader.
Any of the PIE KDZ threads I maintain has the Pie compatible Dev Patched LGUP.
For bootloader unlock, read this:

I told you how to find it. Any of the KDZ threads I maintain in the ROMs section.
Or go to the Frankenstein instructions. Attached there also.
I'm on my phone so you have to go do some looking.

Yes, it means you either are not using the most recent Dev Patched LGUP or you didn't install it correctly.
See LGUP in post #2 or #3 of this thread, among many other places. Read the Installation instructions. Uninstall any prior version.
