I had something like this a while ago. Check that the trimming is in the middle and not trimmed so far to one side that it's in the next gear. Doing the factory/crash reset procedure set the trim back to the middle and I was able to reach all the gears again. Worth a try.

I asked about the trim a couple of posts back.

Thanks, it's not trimming as I have trimmed it as far as it will go and it's not enough.
When you have it wired up to e tube it tells you what trim position you are in and you can adjust it on the computer (I didn't know you could do all this until last weekend).
But I messaged LBS last night and his suggestion was it might be something to do with crash protection. I'll see if I can trigger crash protection and if that might reset it.

It's not reaching the high limit, it won't even reach the smallest sprocket.
I tried backing off the limit but it doesn't change anything. It's not the limit which is stopping it, it's its belief that there isn't another gear there / lack of the final click.
I'm pretty certain it's a software fault rather than hardware. Maybe I need to get on to shimano. Well out of warranty though.
