Backup the configs ComfyUI\user\default\comfy.settings.json and ComfyUI\user\__manager\config.ini, relaunch Comfy, then manually set all the settings back to what you had, making sure to set the Comfy>Settings>Live preview method to auto or what ever you want. It fixed the problem when I had it.

What do you mean, deleting those files?
I have to add, that each time I reload comfy "preview setting" goes back to "none"
Having it switched "on" in settings, doesn't do anything
Go to Settings and change live preview method

Thanks for the tip, but still not working :/
Same issue. I'd initially set it to latent to rgb inside comfyui manager and it had always just worked. Latest update broke it. Noticed the setting had been turned to NONE, so I switched it back to latent2rgb, but still nada.
you can try to print in latent_preview.py what method is set (in def get_previewer(device, latent_format))
Mine also doesn't show the preview image after the update.
Launching with 'python main.py --preview-method latent2rgb' fixed it for me. At least I think that's what made it work. :D
yeap adding it also solve it to me

yup we have to find solutions for the things that was working perfectly , while they just fixing the thing which was working nicely
why is so much stuff breaking, this is getting real tiresome. never updating again
With every update, something breaks because they don’t even bother testing it before release
If you are on the portable version adding
--preview-method auto
to the run_nvidia_gpu.bat also works

This works
The runtime live preview configuration has been migrated from ComfyUI-Manager to a native feature of ComfyUI. I apologize for the lack of sufficient guidance during this transition.
After updating to the latest ComfyUI-Manager (v3.39), if your ComfyUI version natively provides the live preview feature, the preview method option in ComfyUI-Manager will be automatically disabled, and a tooltip will be shown to guide you.
