I updated Minecraft Java to 1.20.5, but the creepers dont drop gunpowder in this version.

I updated Minecraft Java to 1.20.5, but when i wanted to use my mob grinder, the creepers didn't drop gunpowder, i killed about 30 creepers, but no one dropped a single item.

What I expected to happen was...:
To get gunpowder from creepers of my mob grinder.

What actually happened was...:
I didn't get gunpowder with my looting 3 sword, i killed more than 30 creepers without any drop.

Steps to Reproduce:
Update to 1.20.5 (Java Edition) from the official launcher and try to get gunpowder from creepers
