What version of Codex is running?

codex-cli 0.45.0

Which model were you using?

gpt-5-codex high

What platform is your computer?

Darwin 25.0.0 arm64 arm

What steps can reproduce the bug?

Ask codex to build a dotnet solution

• Ran dotnet build Main/Main.sln
  └ failed in sandbox: CSSM_ModuleLoad(): One or more parameters passed to a function were not
    valid.

I get this output from codex

but somehow codex is able figure out a way to circulate this, but it always fail at first and try multiple times. I think it is a waste of token/compute, so filing a bug report here.

What is the expected behavior?

It should be able to run dotnet build

Or at least provide a clear instruction on what folder we need to whitelist in writable_roots to allow it to work

What do you see instead?

failed in sandbox: CSSM_ModuleLoad(): One or more parameters passed to a function were not
    valid.
