After upgrade my macbook pro to big sur 11.1 app store app shows a new xcode version (12.3) is available. I click on update button and it stays there forever, progress bar never moves.
I've already rebooted the system just to be extra sure and it keeps doing the same.
MacBook Pro 15″, macOS 11.1
I can confirm the same behavior. Mine initially downloaded and the progress bar stalled at around 80% on the visual.
I checked LaunchPad and saw that the app was completely downloaded but not installing.
I tried a reboot since it was hung up and since doing that Xcode 12.3 will not even begin to download.
Alternate download is here: https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_12.3/Xcode_12.3.xip
xcode 12.3 never downloads on big sur 11.1
