In this case it's to replace RGB values to equivalent hex colors, and back. Claude has never failed me until today... but unfortunately my script is causing Npp to spit out an `PluginsManager::runPluginCommand Exception - Access Violation` popup:\n\n\u003cimg width=\"370\" height=\"186\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/461c4e59-0ee2-420a-ae68-fc1985528d3c\" />\n\n\n# How can I debug this?\n\nThis is really frustrating to diagnose because even though I have the \"**`Show Console`**\" enabled for PythonScript globally, it doesn't seem to show the error in the console at all, and I have no way of knowing what line or specific section of code is throwing this error.\n\nAll of my old scripts work completely fine, so I don't think this is an installation issue. Can someone possibly spot what's wrong with my script or at least provide me with a better way to debug this? I have no clue what to do in order to diagnose this bug.\n\n\u003cimg width=\"1200\" alt=\"Image\" src=\"https://github.com/user-attachments/assets/0d6ff608-cb3a-4356-b917-dc874510d768\" />\n\n\n\n# My Scripts\n\nHere are both scripts:\n\n- [FM TransformColorJsonHexToRgb.py](https://github.com/user-attachments/files/25087424/FM.TransformColorJsonHexToRgb.py)\n\n- [FM TransformColorJsonRgbToHex.py](https://github.com/user-attachments/files/25087425/FM.TransformColorJsonRgbToHex.py)\n\nThis is my input (I've tried running on selection as well as the whole file):\n\n```json\n{\n  \"Name\": \"Some Name\",\n  \"BackgroundColor\": \"22, 22, 24\",\n  \"LightBackgroundColor\": \"19, 19, 21\",\n  \"DarkBackgroundColor\": \"14, 14, 15\",\n  \"TextColor\": \"227, 227, 239\",\n  \"BorderColor\": \"39, 39, 42\",\n  \"CheckerColor\": \"213, 188, 170\",\n  \"CheckerColor2\": \"212, 146, 146\",\n  \"CheckerSize\": 17,\n  \"LinkColor\": \"95, 136, 255\",\n  \"MenuHighlightColor\": \"44, 44, 52\",\n  \"MenuHighlightBorderColor\": \"28, 28, 34\",\n  \"MenuBorderColor\": \"28, 28, 34\",\n  \"MenuCheckBackgroundColor\": \"186, 219, 130\",\n  \"MenuFont\": \"Roboto, 14px\",\n  \"ContextMenuFont\": \"Roboto, 14px\",\n  \"ContextMenuOpacity\": 100,\n  \"SeparatorLightColor\": \"255, 75, 238\",\n  \"SeparatorDarkColor\": \"25, 25, 28\"\n}\n```\n\n## `FM TransformColorJsonRgbToHex.py`:\n\n```python\n# -*- coding: utf-8 -*-\n\"\"\"\nRGB to Hex Color Converter for Notepad++ PythonScript\nConverts RGB color values like \"22, 22, 24\" to hex format \"#161618\"\nHandles selection or entire document with full undo support.\n\"\"\"\n\nimport re\n\ndef rgb_to_hex(match):\n    \"\"\"\n    Convert an RGB string match to hex format.\n    \n    Args:\n        match: Regex match object containing RGB values\n        \n    Returns:\n        Hex color string in format \"#RRGGBB\"\n    \"\"\"\n    try:\n        r = int(match.group(1).strip())\n        g = int(match.group(2).strip())\n        b = int(match.group(3).strip())\n        \n        #
