Portal custom server lags,rubberbanding and crashes.

Hello,

I am wring regarding an issue that is not since yesterday,it happens since December-namely I created custom portal server in Godot and used blocks and since that time I have lags ,rubberbanding and crashes but now since new patch is less often.No matter how many objects I use in project,no matter who has a host (I tested on 7 different hosts),no matter what blocks I use- complex or simple,I even use 38 Vehicles max on thge map-ALL the time I have lags,rubber banding and crashes when is around 55+ people on the Server.Pls fix this because is so annoying and all my players abandoned my server:/ I uploaded an example video what happens on the server:
