I had the same issue with my X-T20 with a kit lens. I never had the issue with any other lens. I put that kit lens on my X-T5 and started getting the same message. In my case the kit lens was the issue. I went through cleaning the contacts and nothing worked. I would suggest trying other lenses (if possible) to verify the lens.

When I first bought my X-T5, i loved it (upgraded to firmware 2.10), and everything worked as advertised. Autofocus on Fuji's not as good as my Nikon or Sony cameras, but it worked for me. I could take pictures of dogs in my backyard, grandkids, etc., now it does not work since upgrading to firmware 4.0. May Fuji sits a corner now, unless I want to use some manual lenses, manual focus works fine. Focus box lies even in single focus mode, let alone continuous focus mode or subject detection. A lot of the softness is from the focus box being wrong. I've been a Fuji shooter since my X-T20, but I'm really considering going back to Nikon or maybe even Sony. I don't know if the issues affect every X-T5 or just selective cameras, but it's obvious Fuji cannot fix these issues. Fuji's are not as clinically sharp as the newer Nikon's Canon, Sony, etc, so you hear the terms vintage or maybe retro to describe the softness in Fuji's photo's. Fuji just seems interested in selling new cameras (with the sam issues) to new users, not taking care of their base.
