.NET 4.8控制台程序手动正常，自动化启动TLS握手失败求助

我遇到一个棘手问题，已经困扰一两天了：

我有一个升级到.NET 4.8的老旧控制台程序，通过HTTP请求连接Broadsoft服务器。手动双击启动时，程序能正常和服务器完成TLS 1.2握手；但通过PowerShell、Python脚本或Batch脚本启动时，会抛出错误：

A fatal error occurred while creating a TLS client credential. The internal error state is 10013

环境配置 #

• 操作系统：Windows Server 2022 标准版
• 组策略已禁用TLS 1.0和TLS 1.1
• .NET程序已完整升级至4.8（包含所有依赖项）

已尝试的解决方法（均无效） #

• 设置PowerShell会话的TLS 1.2标记（仅对PS自身请求生效，不影响启动的.exe程序）
• 以管理员权限运行自动化脚本
• 使用拥有桌面交互权限的特定用户身份启动程序

已尝试的Python脚本 #

import subprocess
import time

# Path to the console program executable
console_program_path = "S:\Broadsoft\Broadsoft_CC\Broadsoft_CC.exe"

# Open the prompts text file
with open("S:\Broadsoft\Parameters\Parameters_CC.txt", "r", encoding="utf-16") as prompts_file:
    prompts = prompts_file.readlines()

# Run the console program using subprocess
with subprocess.Popen(console_program_path, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True) as process:
    for index, prompt in enumerate(prompts):
        process.stdin.write(prompt)
        process.stdin.flush()

        # Wait for a limited time to read output from the subprocess
        timeout_seconds = 2  # Adjust this timeout as needed
        start_time = time.time()
        while time.time() - start_time < timeout_seconds:
            # Non-blocking read from stdout
            output = process.stdout.readline().strip()
            if output:
                print(output)
                break  # Exit loop if output is read
            time.sleep(0.1)  # Wait a short interval before trying again

        # Add an "Enter" keypress after the last line
        if index == len(prompts) - 1:
            process.stdin.write("Start()\n")
            process.stdin.flush()

# Close the process and streams
process.stdin.close()
process.wait()    

恳请各位提供排查方向或解决建议，感谢！
