TestComplete update 15.56.2.7 has stopped any browser responding (6 tested)

Hi,

 

After the TestComplete update to 15.56.2.7, I can't run any of my tests

 

I can populate the URL bar but not interact with anything in the browser window, when I record a new test it shows like name mapping doesn't exist or the browser is one object

i.e., a button press is recorded as "Aliases.browser.BrowserWindow"

 

- I have checked the engines and in 3 different browsers but no luck identifing the issue

 

I updated 2 machines at the same time - both exactly the same configurations and one machine has stopped working

 

has anybody else experienced this loss of functionality?

- TestComplete is now completely unusable for me
