Codex can't read files

I think this is new since 0.99, Codex in Windows runs Get-Content README.md and gets nothing back.
Sometimes, if pushed it will say that it can do it with escalated permissions. When asked, it said "I then retried with sandbox_permissions: "require_escalated" (you approved it)." Although I didn't see any approval request.

This had been working fine for quite a while, I don't think I've changed any permissions that should break it. My config.toml:

sandbox_mode = "workspace-write"
personality = "pragmatic"
model = "gpt-5.3-codex"
model_reasoning_effort = "medium"

[sandbox_workspace_write]
network_access = true

[features]
powershell_utf8 = true
elevated_windows_sandbox = true

[tui]
status_line = ["model-with-reasoning", "current-dir", "context-remaining", "five-hour-limit", "weekly-limit"]

Another quote from Codex: "I’m currently unable to read files from this session because every shell command is failing with no output (including Get-Content, Get-ChildItem, and pwd)"
