Ask for help: Backend quit unexpectedly about diffusionbee-stable-diffusion-ui

[holygrolli]

Had the exact same error. I realized my internet connection filter (TripMode) blocked traffic of this unknown app. After enabling internet access for DiffusionBee it started downloading the model.

Happened to me, just quit and restarted and all was fine

I quit and restart for many times, but still not work.
So I try to find a way.

I'm having the same issue on M1 Pro MacOS 12.6, with this error.

Uncaught Exception:

I'm seeing the same on 12.6
Uncaught Exception: TypeError: Object has been destroyed at IpcMainImpl.<anonymous> (/Applications/DiffusionBee.app/Contents/Resources/app.asar/background.js:2:240352) at IpcMainImpl.emit (events.js:315:20) at Object.<anonymous> (electron/js2c/browser_init.js:161:10307) at Object.emit (events.js:315:20) at ChildProcess.<anonymous> (/Applications/DiffusionBee.app/Contents/Resources/app.asar/background.js:2:244979) at ChildProcess.emit (events.js:315:20) at maybeClose (internal/child_process.js:1048:16) at Socket.<anonymous> (internal/child_process.js:439:11) at Socket.emit (events.js:315:20) at Pipe.<anonymous> (net.js:673:12)
I'm on an M1 Pro with 32GB RAM. Let me know if you need anything for debugging.

Also saw the same issue and same error. Mac Mini M1. Fresh install of 12.6, restarted and reinstalled DiffusionBee several times. Same message.
Resolved by deleting current install of DiffusionBee, restarting, reinstalling DiffusionBee without opening it, full restart, then opening. Appears to run well now. : )

I am seeing the same issue and the same error. Attempted the same restart options noted above including deleting, restarting, reinstalling, not opening, then restarting again. I still see "Backend quit unexpectedly" in addition to the following:

A JavaScript error occurred in the main process

This is all occurring on a Macbook Pro M1, 16GB RAM, recently updated to Monterey 12.6 (updated in order to run this specific program). Happy to pass on any other helpful information.

EDIT This problem resolved itself spontaneously after 24 hours without restart.

Same issue here.

MacBook Pro 16inch 2021
Apple M1 Max
64Gb RAM, most other apps closed
macOS 12.6

I can confirm the blocked internet access is the solution.

[mattq2022]

How did you "unblock" the app? I have allowed in the firewall and even tried turning the firewall off; neither worked

[allanjackson]

Download the 1.4.3 version, that should fix this issue.

[mattq2022]

Yeah, I have a intel Mac, so the newer versions do not work

[anshuzy]

Hey! I just installed the latest version of Diffusion Bee 1.5.1 and this is the exact error that's happening to me. The models just refuse to download. I tried all of the steps that you guys said and it still isn't working. Anyone have an updated solution?
Specs: M1 Pro, 16gb ram, MacOS 13.0.1

Hey! do you know any other possible fixes? I just updated to Monteray just for this too and it's still not working for me even after all the restarts and redownloads.
