Roblox Update broke my simple small portion of a script. Need a small bit of help?

I'm sure you all people of the new roblox update, the one with the dramatic grey logo. Well, they not only updated the website but also the studio! Making prints look more nice and clean, and breaking tons of scripts when talking about server managing objects or values inside player.

Didn't realize it yet? Here's a small portion of my script, which is in workspace called datastore.

FE is on by the way.

Well our good friend "datastore" is going to save and load values in and out of our player, but whoops! Roblox update prevents you from doing that anymore. When in Client Mode, I can see a folder I made with a script called "PlayerEquipment" (Saves a bunch of critical values I need for the game to function correctly), but when entering Server Mode and go in the player in workspace, guess what? There's no "PlayerEquipment" folder! So the script, gives me an error when trying to look for it. This also applies to when looking into values inside the player through the server

Script:

--Code 
player.Character:WaitForChild("PlayerEquipment")
--Code

Output:

Infinite yield possible on 'Workspace.wilsonsilva007:WaitForChild("PlayerEquipment")'

I'm unsure if this is an issue that roblox will discuss or if it's going to be like this always even tho because the update is brand new. What was the point of this update anyways? Probably prevent exploiters hacking? At what cost? Breaking scripts and games freatures?

I cannot carry on coding while this is like this, or atleast, while I don't know how to save these values without getting an error.

Any ideas on how to fix this? What's your throughts? Do you think it's a good improvement to roblox anti-exploit?

Thanks for your times guys.
