Space-related issues, including this one, have very few solutions that users can resolve on their own.
One workaround is to create a completely new Space and re-upload the same source code, but this will result in the loss of commit history, community posts, and likes.
Therefore, if you encounter an issue that appears to be related to Hugging Face’s servers with a Space you have been using for an extended period, it is recommended to send an email to Hugging Face with your account name and a detailed description of the situation. website@huggingface.co
