Realms disconnecting all players and not saving progress

Every time I or another player log into my realm and build something the realm disconnects all online players after 15-20 minutes and reverts to the last save, this issue only happens when someone places a block, if a player joins the realm without building anything there are no issues, this is quite frustrating as i am effectively paying for an already restricted realm running on quite under powered hardware for its application with restrictions like 16 chunk render distance and only 10 max players that I cannot even build on without watching my progress get wiped away after 15-20 minutes and many other players had and still are having this issue on an off off basis since 2018

I have a stable internet connection and my hardware is plenty powerful enough for my 300mb world file that im running on the realm
