Xcode 12 crashes upon opening Developer Documentation in Window menu

Xcode 12 crashes upon opening Developer Documentation in Window menu on macOS Catalina 10.15.6. Can't view documentation at all in Xcode. Is there a workaround to get this to work? This is a fresh install of Xcode 12 from the App Store.

It isn't an amazing workaround, but most, if not all of the Swift documentation can be seen on the swift documentation website. Link here: https://swift.org/documentation/

After downloading the Xcode_12.xip file from Apple downloads, I am getting this Archive Utility error: "The operation couldn't be completed. Block-compressed payload operation failed."

What can I do to get the xip file to uncompress properly? The man page for xip in Terminal doesn't really help.

I do a lot of work when Internet is not readily available. Offline Xcode local documentation and a lot of other info is crucial. Assuming a lot of Internet connectivity is perhaps risky, a lot happens without it.
