[!] Oh no, an error occurred.

Search for existing GitHub issues similar to yours:

To use the latest version of Fritz you’ll need to
Upgrade to Xcode 11.4 or later.

After upgrading to Xcode 11.5 I get the same error message.

I actually think this is a CocoaPods issue. Can you try following the steps posted at the bottom of the Github issue you linked to:

Runningsudo rm -rf ~/.cocoapods/repos and then pod install.
