can't load new chunks as correctly on 1.12.2 / 1.16.5 servers

[CayanNet]

Describe the bug

this is happening when the bedrock players (1.20.40 ~ 1.20.73) tried to load new chunks on 1.12.2 / 1.16.5 server they get messive fps drops with high pings and lead the timeout the player and memory & cpu usages as high as it can (geyser velocity)

To Reproduce

1. join the 1.12.2 / 1.16.5 server
2. try to load the new chunks
3. get messive fps drops + high pings and get timeout + velocity goes crash with java heap spaces (high ram & cpu usages as almost 100%)

Expected behaviour

after i get fps drops / high pings i get timeout from server and velocity goes high cpu & memory usages to crash itself

latest.log
this is the 1.12.2 server log with rtm516 when we tested about this issue and yeah u can see he got timeout after that

https://pastebin.com/C9Vz1kXC
this is the velocity log after when rtm516 got timeout ofc it kicked all of players in other servers since of velocity got crashed (i was allowcate the ram of velocity has 2gb it can deal the more than100 players in 1.20.4 as i tested with 2gb but how the 1 player in 1.12.2 / 1.16.5 server can crash velocity)

+1, having this issue on Geyser for Velocity and it kills the server. Using WorldEdit when there are Bedrock players online also keeps slowly filling up the memory usage until it crashes, not sure if that's related to this bug.
