1.20.1 Version 1.4.147 Tps Lag

[Winkxzs]

I am running a 1.20.1 12gb Premium Server
When ever someone joins/loads In a chunk that has Chiseled blocks It causes a lot of Tps lag, Around 45-200 Ticks behind.
Also whenever someone joins with Chiseled blocks in the area it causes other players to lag while they load.
And when joining a chunk that has Chiseled blocks, They are invisible for the first few seconds
I don't know if this is just normal for C&B
