Please let us copy & paste your existing regular expression and don't let us type it character by character.  
Your screenshot is fine, but please add the regex formatted as code like this:  
`(?i)(\s)f(?:ea)?t(?:(?:\.?|\s)|uring)(?=\s)`

BTW:  
If you use a [code snippet from this forum](https://community.mp3tag.de/t/featuring-all-derivatives/9445/4) please read the exact use case.  
This one is for some derivates of "featuring" **if it is has a leading space**.

Your example has an opening bracket (not a space) in front of "Featuring".

And your replacement text has also a space in front of `␣feat.`  
This would make "20 Broken` ( feat.` Amy Lee).mp3" if it would match at all.
