Hi @sifutech,
I hope you're doing well. Make sure that you have the latest version of Fusion 360 installed. Let me know how you are trying to upload the library. A straight upload should only be done with local libraries, managed libraries follow a different process.
Let me know if there's anything else I can do for you.
Best Regards,
