Ctrl+Shift+P → Output: Show Output Channels → 选择 Codex 相关通道，查看日志信息，复制给AI

如果是Codex process is not available这个错误，需要安装https://aka.ms/vs/17/release/vc_redist.x64.exe，即可使用

I've hit the same / a similar issue.

Depending on the Linux environment, the desktop entry may call /usr/share/code/code directly, whose zygote processes could inherit RLIMIT_NOFILE=1024. The Codex webview preloads enough resources concurrently to hit that limit and stall during startup.

Starting through /usr/bin/code may raise the zygotes' soft RLIMIT_NOFILE limit to the hard limit (524288 on that system), which their renderer children inherit.
