Thornless berry?

Whilst clearing the brambles at the rear of where my new shed will be I came across this? It looks to be some sort of thornless berry? and I just wondered whether it was worth keeping?
Does anyone have any idea what it is?

Could be a tayberry, loganberry or one of that family. I have several but no idea what they are now. Wait until it flowers for a better idea. I'd keep it.

I've got a thornless blackberry, so you might be lucky and get something good. I'd keep it too.

Could it have come from the garden next door ?

I'll be honest I remember planting a berry somewhere up that fenceline (thought it was higher up though?) a couple of years ago. I can't remember whether it was thornless or not and I think it was probably a Loganberry. If it was that, it hasn't made much growth especially as they are supposedly rampant aren't they?

Maybe it was struggling against the brambles? Or maybe it has tip rooted from its original position. I have a few that wander around, aimlessly - like me.

I got a red gooseberry, Autumn Raspberry,Summer Raspberry, Tayberry and a Blueberry. I wanted a loganberry but couldn't see any?

Anyway when I got home I took delivery of Senshyu ,Autumn Champion and Radar onion sets all boxed and packaged nicely and and in individual mesh bags from Simply Seed.

My plant ID app says raspberry, but I think the leaves are a strange colour for raspberry... but I might be wrong.

Could be, but if so, it hasn't grown much since 2021?
