2nd time it’s happening, first time there was some folder that was missing in the comfyui folder, so I just manually made it and it worked. Now today at first it says ‘C:\Users\Me\Desktop\ComfyUI\models\user is not a valid directory.’ Reinstalled again, but deleted the 2 appdata folders as instructed by you guys, and now it says FilenotFoundError: [Errno 2] No such file or directory: ‘C:\Users\Me\AppData\Roaming\ComfyUI\extra\_models\_config.yaml’ Error: Python process exited with code 1 and signal null please advise ---

Is there a way to fully uninstall? All the times I reinstalled it never asked me to specify a preexisting models path like it did the very first time. Which, by the way might not work as it should. I tried installing ipadapter after my first installation and comfy couldn’t see the models even though I copied the files to every comfy models path I could find. So even if I specified for it to use my a1111 models path at the installation, it wouldn’t see the ipadapter models until I manually changed the yaml paths file. Removing the 2 app data folders specified here doesn’t work after uninstalling from windows: [Your connected workspace for wiki, docs & projects | Notion](https://comfyorg.notion.site/#dde78c93ce00412d94ca63618c1ee47a) Edit: Nevermind, missed the 3rd folder, it’s full reinstalling now, I opted out of the model folder migration and will do it manually through the yaml file, reinstall ipadapter, and restart comfyui desktop to see if the error comes back. ---

Ok, so far so good, I’ve restarted my comfyui after setting everything up and there’s no errors as of now. ---
