How to stop the screen from flashing?

WiFi Diagnostics Keyboard Shortcut in macOS Catalina

It looks like cmd+ctrl+option+shift+w triggers a WiFi Diagnostics session.

Browse to /Private/var/tmp and you'll see 300MB+ files titled WiFiDiagnostics_YYYY-MM-DD_IP4-address_Mac OS X_MacModelName.tgz

I can't find any official documentation on this, and I believe this is new for Catalina.

Unfortunately, I don't yet have a solution to this problem. I can confirm that it manifests on my Catalina system as well. I wanted to add a comment but don't have enough reputation (any advice on how to better approach this is welcome).

Back to the issue at hand, on my 13" 2019 Retina MBA I can see the same problem. It is as if we're pressing a magic combo which seems to trigger a debugging session of sorts. The processes related to this, that I could find, are footprint, lsregisterd, spindump, system_profiler, sysdiagnose and wifivelocity. On this system, being a 2-core one, the CPUs go up to 100% and sit there while these processes run and do their thing. I had to resort to some shell magic to kill these to make it stop faster.

I have also asked a friend to press the combo on a 2016 MBP and I can confirm the system did the same thing, screen blinking, footprint process running, etc.

Does anyone have an idea on being able to reclaim this shortcut?
