Thanks for reporting. There is a known issue with Gemma3 1B which we have not addressed yet, but it's being bumped up the priority list.
In the meantime, would the 4B version work for you instead?

Thanks for the confirmation.

Indeed 4b-it-sfp.sbs works fine and is a viable alternative for my experiments.
