Version 1.20.73.01 didn't solve the issue on my side (Windows server). It as the same faulty behavior as for 1.20.71.01 and 1.20.72.01. The players can connect to the world, but is promptly disconnected, making it unplayable.
This also occurs on version 1.20.72.01.
Same here. The error appears a few seconds after a player login on the server.
Same issue here, running bedrock server on Windows. keepinventory is always false when starting the server.
