[Clio]

Hello,

I am hoping someone might be able to give me some advice. I have been adding some kindle books to my Calibre library. Everything worked perfectly just yesterday. But when I tried to add some more books this morning, I am getting this error message.

Please does anyone know why this is happening, and what I can do about it? I'm confused because everything was fine just yesterday, and I haven't changed anything.

Thanks in advance for any help!

calibre, version 5.40.0
