"ResultRes": [
{
"id": null,

"type": "json",
"value": "{\n \"$schema\": \"http://json-schema.org/draft-07/schema#\",\n \"type\": \"object\",\n \"properties\": {\n \"product_name\": {\n \"type\": \"string\",\n \"minLength\": 1,\n \"maxLength\": 100\n },\n \"color\": {\n \"type\": \"string\",\n \"enum\": [\n \"Red\",\n \"Green\",\n \"Blue\"\n ]\n }\n },\n \"required\": [\n \"product_name\"\n ]\n}",
"storeId": null,
"failResult": "not satisfy",

I can reproduce a very similar freeze in Codex Desktop when pasting JSON that contains a nested escaped JSON string.

Example pattern:

{
  "decision_details": {
    "fallback_reason": "RouteDecisionAgent JSON is invalid",
    "fallback_details": {
      "error": "Extra data: line 37 column 1 (char 1130)",
      "json_text_preview": "{\n\"route_drafts\": [\n{\n\"route_id\": \"main\",\n\"profile_name\": \"综合平衡路线\",\n\"items\": [\n{\"purpose_id\": \"classic_park\", \"visit_purpose\": \"经典公园游览\", \"poi_id\": \"B00140BNNF\"}\n]\n}"
    }
  }
}

Same thing here, on my macbook, I cannot paste anything and I find myself complmeting the task in claude code because it's impossible to have anything pasted into codex.
Please fix this bug asap? This is a real headache!
