How do I stop this from happening [bedrock] ps5/pc

Hello. This is unbearable. I have tried everything suggested in previous posts that doesn’t involve migrating to 3rd party. Below is a list of everything Ive found.

I have a Realms Plus subscription. It has been active 5 years and has 4 consistent players. We are recently experiencing severe lag issues with the realm to the point it is unplayable. Blocks cannot be placed, eating food takes 3-4 times to register and entities, arrows, items and amore wont register being picked up for long and or move extremely slowly and judder.

The Ream has 11 addons which are as follows:

• Redstone Add-On (1.1) by Pixelbeister

• Magic Add-On by Pixelbeister

• Tinkers Construct Add-On by FTB

• Essentials by Unlinked

• Basic Machinery by Vatonage

• Inventory Manager by Mythicus Studios

• Redstone Tech by Vatonage

• Trains Add-On by LifeBoat

• Alchemy by Unlinked

• TNT Add-On by Rareloot

I have tried extensive testing to see if I can find a source of the issue and here is what I have found:

The addons are not the cause as i have taken all of them off and re uploaded the world to test this and the lag remained.

Large amounts of entities are not the issue as we have no large farms of clusters of entities, nor do we have any persistent Redstone contraptions going on. We have built some structures over 5 years but nothing particularly large and overbearing or dense. I have also used command blocks to check for entity spam and nothing notable comes up.

I have tried making copies to reupload.

I have reduced all entities like chests and signs as well to an absolute minimum.

All players have adjusted their graphics settings to the lowest impact.

We have tested many different server location options available for selecting in server settings to no avail.

The realm is only 613mb

Official Mojang support has been useless

It is at this point that I am at a severe loss. It is my thought that there may be issues on the hosting end of things? Server side? I have done everything suggested to me that i can and my own investigations and cannot find the cause.
