Critical App Launch Crash: Electron Remote Uncaught Exception in Main Process After Update

[lekkerwarm]

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.

Uncaught Exception:
Error: "@electron/remote" cannot be required in the browser process. Instead require("@electron/remote/main").

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…’

TIMING SUCKS!!!

I agree users should have the option of updating…

@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

Use at your own risk - uninstalling may result in losing local cache…
