I am also seeing this issue

[elseLuna]

I ran into this issue and managed to track it down to C:\Users\<username>\.cache\huggingface\hub\models--openai--clip-vit-large-patch14\snapshots\32bd64288804d66eefd0ccbe215aa642df71cc41\special_tokens_map.json being corrupted.

I fixed it by deleting the models--openai--clip-vit-large-patch14 folder and restarting the webui to redownload it.
