Additional information
Further debug. I have been working on a project/thread in PlayGround for a week. If I move this project/thread folder out of the PlayGround folder then codex seems to start fine. This project has a lot of code in it, but why would codex close because this project is in the playground folder??
Further debug (2). If I move the .git to .git-bak or similar. Codex starts. This seems to be choking on the .git repository somehow. My git diff --cached doesn't show anythign so this is different from other issues people saw.
(3): when I ran " git ls-files --others --exclude-standard | head -200", it showed quite a few files, including some .wav files. I added those to the .git repository and now codex runs fine. Seems like we a codex git bug where it gets confused on uncommitted files of certain types. Please fix.
(4) the problem is now back. I had to do the "git ls-files" to fix the items not committed. This was just a few .cs text files. I committed them and now codex works again. PLEASE FIX the CODEX .git repository code.

I have wsl enabled, and wsl distros are installed (and working).
We haven't released a new version in the last few days, so this must be related to some configuration change on your system.
Thanks, yes I found codex and see it hasn't updated since Mar 27th. I was working on an app yesterday for most of the day. Codex was 100% stable. The only major config change I made was to give codex full access. Maybe codex munged its own file.
I had this issue after I committed some files to git on a project I was working on. Fortunately, I didn't have any history in git, so I just deleted my .git folder and Codex started working again.
Edit: I see some others mentioning large repos. In my case, it was not a particularly large project. Only about 30 files.
Same, my repo is fairly small. Maybe 60 files or so. I found ignoring libraries, and checking in changed files helps codex not crash.
That makes sense, the only thing what I did was “git” before codex crashing…
