Diamonds not spawning

Hello, I am having a hard and difficult time finding diamonds. Usually when you go below a certain level, such as 0 to -64, diamonds spawn the best there. However, before this hotfix, I was able to find anywhere from 4-8 to 10-12 ores of diamonds in caves anywhere from -38 to -55 (Before I hit lava) Now diamonds are extremely rare and are only 1-2 ores instead of 4-8 ores. We had this problem back in 1.17 where diamonds are extremely extremely rare.
