The issue with SSH not being enabled correctly in Imager is a known bug and is being addressed.
You probably have a good idea what has gone wrong, but I can add that this seems to be a regression relative to a recent nightly beta that I was able to download, flash and ssh into without error.
The image I was working with was 2025-09-14-raspios-trixie-nightly-arm64.img.xz
I have just re-flashed that nightly beta using Imager v 1.9.6 on a RasPiOS Bookworm workstation and it still boots my RPi[5] and comes online via ssh as expected.
