The latest version 1.2.1 beta 5 of Bambu Connect is broken on Intel macOS. - A JavaScript error occurred in the main process

  • Tested on multiple macOS versions (15, 14), both Intel and ARM, on physical machines and VMs
  • Windows version works fine
  • ARM macOS version works fine
  • The previous 1.2.0 version works fine on Intel macOS

The application crashes on startup:

A JavaScript error occurred in the main process
Uncaught Exception:

I believe this issue is caused by incorrect V8 bytecode in Electron.

I know this topic has already been brought up before, but I’ve added some useful information.
Is it possible to contact the developers directly?
I tried opening a support ticket, but the support agent doesn’t seem to understand the issue.
