Please fill in this bug report template: **Lexicon version** : 1.11.0 (+ all other versions are affected because of the aggressive auto-updater) **Operating system (remove one)**: MacOS 26.5.1 (25F80) **Bug description** : After the recent application update, Lexicon crashes immediately on startup with a JavaScript Uncaught Exception. The stack trace indicates that `@electron/remote` is being required in the main browser process instead of the renderer process, causing a fatal framework error. ```auto Uncaught Exception: Error: "@electron/remote" cannot be required in the browser process. Instead require("@electron/remote/main"). at 2272 (/Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:357899) at n (/Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:6160103) at 7657 (/Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:363562) at n (/Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:6160103) at 3998 (/Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:6003351) at n (/Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:6160103) at /Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:6160607 at Object. (/Applications/Lexicon.app/Contents/Resources/app.asar/main/index.js:2:6160620) at Module._compile (node:internal/modules/cjs/loader:1484:14) at Module._extensions..js (node:internal/modules/cjs/loader:1564:10) ``` **Step by step to reproduce** : 1. Install an older version of Lexicon or allow the app to fetch the latest available build update. 2. Launch Lexicon from the `/Applications` folder on macOS. 3. The app attempts to initialize, but before the main graphical user interface (UI) can render, it abruptly crashes and throws the pop-up error dialog box containing the stack trace above. 4. _Note:_ Attempting a full data, cache, and preferences wipe (`~/Library/Application Support/Lexicon` and `~/Library/Caches/Lexicon`) followed by a clean reinstall of the latest version from the website results in the exact same crash on launch. **Screenshot** : None - after messing a lot with OS settings I was able to block the application from updating itself and managed to install an older version. I’m not going back for the screenshot - this description should be sufficient. ---

I REALLY recommend enabling users to use a previous version. Bugs happen, but the way this application auto-updates blocks users from using the application entirely until you ship a fix. ---

Seeing the same issue on Windows 11. Tried closing down application completely Performing uninstall Rebooting computer Launching a fresh download of the installer and running it as Admin. Within less than a second, I get the error ‘…“@electron/remote” cannot be required in the browser process…’ link to threads on Discord where others report the same: > **[Discord - Group Chat That’s All Fun & Games](https://discord.com/channels/821024118484893766/1517500693085294622)** > > Discord is great for playing games and chilling with friends, or even building a worldwide community.

@jjoemalone I can totally understand your frustration, this is a mean issue. I managed to get going by uninstalling the application, installing an older version, then launching it with internet disabled (to prevent it from auto-updating). You can download older versions using the “alternative download links” section here: [Download | Lexicon DJ - DJ Library Management](https://www.lexicondj.com/download) Use at your own risk - uninstalling may result in losing local cache… ---
