Error Upgrading to macOS Big Sur

hello everyone,

I'm trying to upgrade my MacBook Air 2013 from macOS Catalina to the new macOS Big Sur. I have a free storage space of about 54GB, but it keeps giving the error (Install macOS Big Sur quit unexpectedly while using the libBaseIA.dylib plug-in).

can someone help?

MacBook Air 13″, macOS 10.15
