Custom style creation error/issue

Hello everybody, I really hope you can help me.

I have been using Claude Pro for a while now, both on desktop and in Chrome.

However, once I try to create a custom style, I always receive the same error: "*Error handling style. Please try again. If the issue persists, try different text or contact support*".This happens regardless of whether I try to create the style via uploading a document or pasting the text. I know that I could also describe the style, but that would not capture as much of my own voice.

Has this happened to you as well by any chance? Is there any solution? I have tried filing a ticket with the Claude support team, but it's been more than a month, and no one has gotten back to me.

Thank you all in advance for your help.
