我尝试使用 Popen() 打开视频游戏《网络奇兵 2》并使其保持打开状态，该进程打开，然后由于访问冲突而在大约 2 秒后关闭。没有窗户被打开。 Python 运行代码没有错误。 没有任何内容通过 stdout 或 stderr 传递。 它的返回代码为 3221225477，这是访问冲突错误代码。 在我测试过的所有其他情况下，游戏都可以正常打开。 这是我正在运行的代码。
from subprocess import Popen
SS2 = Popen(args="C:\Program Files (x86)\Steam\steamapps\common\SS2\ss2.exe")
我尝试使用几个 Windows 调试工具来查看它关闭的原因，以下是它们关闭之前的一些片段。
进程监视器将其显示为它开始关闭之前所做的最后一件事。

我尝试过的事情：在非提升和提升的脚本以及 python 终端中运行代码。在其属性中将 ss2.exe 设置为以管理员身份运行。 将 System Shock 2 目录移动到其他位置。 我已确保 Popen() 适用于其他 Steam 游戏。 在另外 2 台计算机上尝试过。 更新了 GPU 驱动程序。 尝试了新下载的未修改的《网络奇兵 2》副本以及使用 SS2Tool 进行修改的副本。 使用 shell=True 运行。 尝试了 asyncio.create_subprocess_exec 并得到了完全相同的行为。
我需要使用 cwd=("ss2.exe Parent dir") 将 ss2 文件夹的工作目录添加到 Popen() 中。 现在它按预期工作了。
