Same problem (xCode from AppStore)
Had the same Xcode 12 Documentation crash. Now upon downloading the Xcode_12.xip file from Apple downloads, and double-clicking it to expand it on macOS Catalina, I get the following Archive Utility error after stalling for a while about half-way through the decompression: "The operation couldn't be completed. Block-compressed payload operation failed."

What can I do about that? The man page for xip in Terminal doesn't help.
Looks like 12.0.1 is now in the Mac App Store to address this very issue.
Have downloaded/installed Xcode 12.0.1 from Mac App Store. Now, when opening the 'Developer Documentation' window, instead of showing documentation in that window, Safari gets launched showing info from developer.apple.com. Big change! Is this intended/expected behavior?
Xcode 12.0.1 from the App Store fixed this problem; Developer Documentation window now works. Thank you!
