Qt Creator "Unable to create a debugging engine."

SPlatten

I have an iMAC:

macOS       Catalina
Version     10.15.7
iMax        (Retina 5K, 27-inch, Late 2015)
Processor   4 GHz Quad-Core Intel Core i7
Memory      16 GB 1867 MHz DDR3
Graphics    AMD Radeon R9 M395X 4 GB

Qt Creator 4.13.1

Based on Qt 5.15.1 (Clang 11.0 (Apple), 64 bit)
Built on Sep 16 2020 01:17:08
From revision 1da2c1f766

Yesterday I was building, running and debugging, today my system did an system update, today I can still compile and get no warnings or errors. I can run the application, but I cannot debug the application.

When I try to start debugging I get:

19:08:25: Unable to create a debugging engine.

Debuggers:

Name:       System LLDB at /Applications/Xcode.app/Contents/Developer/usr/bin/lldb 
Path:       /Applications/Xcode.app/Contents/Developer/usr/bin/lldb
Type:       LLDB
ABIs:       x86-darwin-generic-mach_o-64bit, arm-darwin-generic-mach_o-64bit
Version:    1200.031.1 Apple Swift version 5.3 (swiftlang-1200.0.29.2 clang-1200.0.30.1)

I suspect my problems are due to the Xcode update which was quit large.

Is there anything I can do?

@SPlatten , Thank god! I ran up "Xcode" and I was presented with a dialog to install additional components which I did and now it all works again!
