Bad vscode regex to replace script tag containing key word causes crash

For a project with many HTML files like this one:

https://ghostbin.co/paste/dngdh

I need to use vscode's regex replace to strip out the NewRelic script tag from each file that has it.

I was able accomplish this with the following regex:

<script type="text\/javascript">\n[^^]*(newrelic)[^>]*>

Essentially this works because the code between the NewRelic script tags does not contain a "^" character. I could have also gotten away with [^#]. Also I had to play with it until I was able to encompass the closing </script> tag, because the NewRelic script contained a "<" operator.

My question is: Could I have written a better regex? I rarely use regex and found myself crashing vscode multiple times experimenting with what I assume must have been more "greedy" patterns?

I settled on this, though it seems to be a very fragile pattern, but good enough to get the job done. However, I would like to know if there is another better pattern (that doesn't crash vscode)?

Thanks for any ideas.
