(At the risk of taking the discussion over further...)
I'm not even connecting to WebUI, and get the following in game at the image generator:

I managed to finally get it to work last night, and I needed a LOT of help from ChatGPT to make sure that I did everything correctly. The first time I tried it, I got the same error as you as well. It's still not fully up and running; I'm having trouble making sure that the style LoRa and pos/neg embeddings are working properly, but I can at least confirm that it's working and can create images for me.
Some tips and/or issues I faced to help you on your way;
1. The user guide was somewhat helpful, but I found that I relied heavily on ChatGPT for troubleshooting. E.g. once I run the webui-user.bat file and it finishes downloading stuff, I would copy and paste all of it to ChatGPT and ask if everything's alright. I did this in every time I dealt with downloading & installing the dependencies just to make sure that it was done properly
2. Make sure the python version you download & install is correct, i.e. 3.10. I downloaded the latest one, 3.14, and it didn't really work and I had to uninstall it
3. At one point, ChatGPT told me to download/install Visual Studio Build Tools (something to do with an error installing insightface), then download/install "Desktop development with C++", including MSVC v143, and Windows 11 & 10 SDKs. Was it necessary? I really don't know, but it works now. Again, I relied on ChatGPT
4. Make a backup copy of the webui-user.bat file before editing it
5. I suggest doing everything from scratch again. Just remember to save whatever stable diffusion models you've downloaded somewhere else so you can quickly cut and paste it back to the correct folder
6. Assuming you did everything right, make sure you still run the edited webui-user.bat file first, give it time to properly load everything, and only then open the modded CoT
I'm mostly a smooth brain with these sorts of things, but if I can do it, you can too. I believe in you!
