Can someone help identifying this Carrera?

And a brand called Field was popular back then

I don’t think it is a Univega. Here’s an old Univega mtb frame number. Also I have not seen a single Univega on the internet with a teardrop downtube

Finally I don’t think anyone will ever find what bicycle this is, it’s near impossible. I have spent countless hours of search on internet and google lens, not now but from years ago. Nothing exactly like my bike ever showed up.
