Additional information

That happened after reinstalling windows. Before reinstall it worked well and nothing happened unless I had faced a conflict with NVIDIA driver. After autoinstallation of NVIDIA driver version 531.18 by NVIDIA GeFroce Experience, my system started to crush every time when Stable Diffusion Web UI was used. Now, With NVIDIA driver 528.49 version, I guess this problem is solved, but suddenly this JSONDecodeError problem appeared and I don't know what am I supposed to do.

I am running on the same issue, "Failed to create model quickly;" followed by "loading stable diffusion model: JSONDecodeError...". I am running windows 10 64bit with a gtx960, 2gb of vram. I had a previous version of the web-ui working on this same system a few months ago. I Tried updating the gpu drivers, cuda, downgrading from python 3.10.7 to 3.10.6, and updating pip... nothing worked so far.

Deleting cache.json and cache.json.lock in the root dir ended up fixing it for me. Was running some code refactoring and it ended up messing up a lot of stuff (all of my embeddings are corrupted yay), and then i was suddenly getting this error.

[ViolentFran]

I tried deleting cache.json already, but it didn't do it for me. I do not have a cache.json.lock file anywhere tough. I am not doing anything funny with the files other than trying suggested fixes. I also re-downloaded it from git multiple times and it's always the same problem.

same problem here to with windows 11

[KeypressHAPPY]

found it, Delete the "huggingface" dir in .cache folder. the relaunch .bat C:\Users\CURRENTUSER\ .cache\huggingface

found it, Delete the "huggingface" dir in .cache folder. the relaunch .bat C:\Users\CURRENTUSER\ .cache\huggingface

This worked for me too! Thank you so much KeypressHAPPY.

Mac User here, I have a similar error, but a different trace. This happens after trying to run prompts in the browser:

found it, Delete the "huggingface" dir in .cache folder. the relaunch .bat C:\Users\CURRENTUSER\ .cache\huggingface

TKU!!! I downloaded the model files again and deleted the following directories C:\Users\kura.cache\huggingface and files cache.json in the root directory.

KeypressHAPPY's solution fixed my issue as well, I wish I knew what caused it in the first place as it was fairly random, but glad to have it working again. Thanks a ton!
