steamworks spacewar

[ISTAR]

Hello everyone, I am developing a steam game recently and using steamworks. In recent days, I have found that I cannot use steamcloud to write data. Even though it could be successfully used before, it has not been possible in recent days.
I also found that there is a game called spacewar in my steam collection. When I use unity to develop steam games, spacewar is always executed.
However, there is a message on the spacewar page showing that my current macos version cannot run 32-bit games.
Does anyone know how to do this? It has been bothering me for many days because I cannot use steamcloud.
