Realms server kicks me after only a few minutes

After the recent 1.19.50 update I have been unable to play for more than a few minutes before getting kicked form the server. The usual pattern is: I attempt to open a chest or a crafting table or my inventory and there is a 3 - 4 second lag time, then when I have closed whatever I have opened and attempt to open something else I suddenly get kicked from the server.
This has been happening since the day the last update was released.
