Question about including a very short-term role on my resume

I started a new line cook position about six weeks ago, but unfortunately, it hasn't been the right fit. I’m concerned things might not work out long-term, so I’ve started looking for a new role.

I’m seeking some advice on how to handle this on my resume and in applications. Should I mention my current job at all? My previous experience as a line cook went really well, and I have great references from that employer—I only left them to take this current opportunity.

I'd appreciate any insight from people who have been in a similar spot.
