@DominikDoom commented on GitHub (Sep 17, 2023):

This has nothing to do with the webui version, but means a yaml wildcard file failed to load due to illegal characters. It shouldn't happen on a proper file since the file load already specifies the correct encoding, so that means the file is likely corrupted in some way.
It sound really similar to this issue: #224

Actually the exact same character position, so it's probably the same offending file.

The user there said it was the following file:

I do have some *.yaml files in my sd-dynamic-prompts folder.
and just before posting this, I stopped and remembered that I was having an issue/ error with a *.yaml file ( was told by creator not to worry about it and ignore it.). so I took care of that by removing affected lines, and restarted SD and all looks good now.
ohh and the affected file was WC-SDVN\2000Wildcards\presets.yaml for any one else having this issue. look at line's 126 -136

But when I downloaded it myself, it didn't happen for me, so maybe it was already fixed by the author at that time.
I'd suggest re-downloading that wildcard pack to get the current version and else trying the advice the other user said.

I have added another safety catch that will prevent the rest of the extension from breaking if this happens, but this doesn't resolve the core issue with the file itself. There's nothing I can do about that from my side, so this file will be missing from wildcard completion if you don't fix or replace it.

I noticed a mistake. It consisted in unnecessary files.
