codex Desktop crashes when opening a conversation – "RangeError: Invalid string length" Hello OpenAI Support, I'm experiencing a consistent issue with the Codex Desktop app on Windows. The application launches normally, but as soon as I open a conversation, it immediately crashes and displays the following error: `` A JavaScript error occurred in the main process Uncaught Exception: RangeError: Invalid string length at jl.write (C:\Program Files\WindowsApps\OpenAI.Codex_26.707.9981.0_x64__2p2nqsd0c76g0\app\resources\...) at Socket.onStdoutData (...) at Socket.emit (node:events:508:28) at addChunk (node:internal/streams/readable:563:12) at readableAddChunkPushByteMode (node:internal/streams/readable:514:3) at Readable.push (node:internal/streams/readable:394:5) at Pipe.onStreamRead (node:internal/stream_base_commons:189:23) `` Issue details: Operating System: Windows App: OpenAI Codex Desktop The application starts successfully. The crash occurs every time I open a conversation. The error appears immediately after opening the chat. I have attached a screenshot of the error dialog.
