Sizing parts is laggy in only my games studio

I didnt word the title very well but i will explain it here

So basicly, when i size a part in my game that im working on, it is very laggy. When i use tween service or just put it in a loop to scale it with size, it gets very laggy and my frames drop a lot. When i went into a blank base plate and did the exact same thing, it was perfectly fine. No frame rate drop. Does anyone know why this happens?

Edit: I am using team create and making a game with my friends. That might have something to do with it idk

hello
can you sent image or video
to help.

Here is the video:

The file was to big to upload it, so tell me if you cant open it

In the beginning i was showing you that the scripts are the same, with one of them having a wait because i wanted it to wait for it to load in. As you can see, when the part that is in the game sizes, it creates a lot of lag but the blank baseplate does nothing

i can upload the video but i can’t join the google drive

nvm i found it, there where to many parts in the workspace and it caused a lot of lag
