I'm unable to reproduce this issue in 1.19. Only arrows shot from crossbows with the piercing enchantment were able to penetrate shields. With that being said, please could you provide some screenshots or videos of this issue occurring whilst the F3 debug screen is enabled? This would assist in diagnosing the potential problem here. Thanks in advance. 🙂
