A bug encountered when loading configuration text via STDIN

[Hylaea]

What version of V2Ray are you using?

5.16.1

What's your scenario of using V2Ray?

Socks and VMess proxy, and Intranet penetration

What problems have you encountered?

A bug encountered when loading configuration text via STDIN. panic: runtime error: invalid memory address or nil pointer dereference

Windows10 Startup script: type vpoint_vmess_freedom.json | v2ray.exe run Centos7 Startup script: cat vpoint_vmess_freedom.json | ./v2ray run

Note: Delete config.json first, otherwise will load configuration from config. json instead of STDIN.

What's your expectation?

The program is able to read configuration text correctly from STDIN, because these configuration text are generated dynamically and do not want to be written to the hard disk.

Please attach your configuration here

Server configuration: The configuration comes from vpoint_vmess_freedom.json

{
  "inbounds": [{
    "port": 10086,
    "protocol": "vmess",
    "settings": {
      "clients": [
        {
          "id": "23ad6b10-8d1a-40f7-8ad0-e3e35cd38297",
          "level": 1,
          "alterId": 64
        }
      ]
    }
  }],
  "outbounds": [{
    "protocol": "freedom",
    "settings": {}
  },{
    "protocol": "blackhole",
    "settings": {},
    "tag": "blocked"
  }],
  "routing": {
    "rules": [
      {
        "type": "field",
        "ip": ["geoip:private"],
        "outboundTag": "blocked"
      }
    ]
  }
}

Client configuration: Same as the server configuration.

Please attach error logs here

Server error log: No log file because the program failed to start.

Client error log: No log file because the program failed to start.

Please attach access log here

No log file because the program failed to start.

Other configurations (such as Nginx) and logs here

None

If V2Ray cannot start up, please attach output from --test command
