CPT and Pages rewrite slug conflict giving me a 404

I’m currently getting a 404 on my site for a page using a CPT archive as the base of its URL.

I previously used this solution to solve the issue – custom taxonomy and pages rewrite slug conflict gives 404 which as been working perfectly.

My issue is now I’ve had a second request for a url which I can’t get to work.

My original code is:

However, if I reuse this code even when changing the filter name etc and the variables I get a website error. I’ve tried several different versions so far and happy to include them if that’d help but didn’t want to make the post too long.

TLDR: I currently have one rewritten URL, however now a second is needed I can’t get the same solution I previously used to work.
