The latest version of Xcode you can run on Catalina (10.15. 4) is Xcode 12.4 and Command Line Tools 12.4.
Support Ending November 30, 2022 In keeping with Apple's release cycle, we anticipate, macOS 10.15 Catalina will no longer receive security updates starting in November 2022. As a result, we are phasing out software support for all computers running macOS 10.15 Catalina and will end support on November 30, 2022.
Per https://developer.apple.com/support/xcode/ , XCode 12.4 is the latest version that runs on Catalina.
Downloading and updating XcodeThe current release of Xcode is available as a free download from the Mac App Store. The Mac App Store will notify you when an update is available or you can have macOS update automatically as it becomes available.
Xcode 11.1 is available on the Mac App Store now so you should probably be using that. Try a force brute approach by deleting Xcode 11, redownload and reinstall.

I was able to work around this by uninstalling Xcode first. What I did:
rm -rf ~/Library/Developer
rm -rf ~/Library/Caches/com.apple.dt.Xcode
App Store and search for Xcode and install it from there.
