Strange, pygame is not usually demanding on hardware and works on any toaster (I'm not talking about performance, but about whether they work).
Pygame, by default, opens a background command window, because it works on python, the creator of the game must disable this, if not, then it is normal for it to appear and close if for some reason it fails to start the graphical environment.
By any chance, what operating system do you have? Pygame runs on python and depending on the version of python used, the game might not work on windows 7 or 8, and only work on windows 10 and 11
I would tell you to use this game that I have programmed myself to test, it is created in pygame 2.x and with python 3.12, I have tested it on a computer that is more than 10 years old, but with windows 10.

The administrator mode and the sandbox should not alter the operation of a well programmed game at all, they are actually basic security tips.
A well designed game (except for very, very few exceptions) should not need administrator mode and the sandbox is used, so that in case a game carries malware or tries to steal some credentials it cannot affect your real data.
