Yeap, I’m having the same issue when trying to reinstall latest 0.4.5 on Windows 10:

[2025-01-14 18:53:55.235] [error] Failed to execute startup-script: C:\Users\Admin\AppData\Local\Programs@comfyorgcomfyui-electron\resources\ComfyUI\custom_nodes\ComfyUI-Manager\prestartup_script.py / type object ‘datetime.datetime’ has no attribute ‘datetime’

I’m using a Windows on Brazilian Portuguese date setup (DD/MM/YYYY instead of MM/DD/YYYY)… Could it be related to it?

My portable ComfyUI is just fine. :slight_smile:

Thanks!

Same issue on the Mac install running 0.4.5 on M2 Apple Silicon:

The strange thing is I successfully installed and ran earlier today, but after initiating a re-start via the manager, started getting this error.

I resolved the issue by deleting my custom node/ComfyUI-Manager. The issue may be in that package.

5

Did you install any extensions / custom nodes between the last good start of the app, and restarting via Manager?

6

No. I think there was a conflict between my original ComfyUI install and the one handled by the desktop app. I deleted the Comfy-UI-Manager from my original install, deleted the fresh install with the desktop app, then re-ran the install without migrating my prior data and problem was resolved. I then manually copied models, VAEs, etc into the new install and was able to see expected behavior when using the Manager to install additional custom nodes.

Excellent; thank you for letting us know! It really is quite helpful.

I had same problem, I deleted ComfyUI-Manager, and also comfyui-animatediff and ComfyUI-AnimateDiff-Evolved from Custom nodes, but I want them back, any idea for solution without deleting those nodes? I am really new with ComfyUI, started with it just yesterday.
