I was able to solve it on a 2016 Lenovo laptop by disabling antivirus until next reboot and pointing my DNSs to Google Ones.
Hope this helps someone else as well.
This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
I've disabled the defender and other software for malware and virus protection and tried moving the executable to desktop and then launching it. I don't have an idea whats wrong with it! Any help is much appreciated.

OK, I now have the media creation tool running perfectly again.
I'm not sure if the fix will work for all but I would like some feedback.
I downloaded Macrium Reflect (Free Version - Home)
https://www.macrium.com/reflectfree
I then created a rescue USB, booted form the rescue USB then restored/repaired the Windows boot system (Restore non-booting systems).
After that all good. Media Creation tool works perfectly!!!!
If a few of you can confirm this is repeatable this would help everyone with the issue.
Please have a go and feedback your results.
It takes less than 5min so worth the investment in time.
Good Luck!!!
Use firefox (or chrome if you must) , look for a "mobile emulator" add on, install and use it to fool MS site you are visiting from a mobile device, get a direct link to the iso.
This was answered before, the MCT cannot run on your PC you may need to use windows update to update your PC.
