I desperately need help

is anyone else having the problem on when they open an old file that has either been downloaded to a usb or is just still on the makecode arcade or downloaded to the laptop and when you do either some blocks are just missing or functions of the game have diappeared or even all of the art and assets have disappeared ?

becuase this has happened to all of my previous projects that ive spent many hours on

Feel free to post an example or two of your problematic projects (links, cartridges [i.e., PNG files], etc.). Perhaps someone here can help diagnose the problem you’re facing.

That did happen to me
