Energy balance

High-intensity interval training (HIIT) elicits higher plasma lactate concentrations than work-matched moderate-intensity continuous training (MICT) during the exercise bout.

If you do HIIT, you will produce more lactate than if you did moderate continuous training of the same work. This is expected and part of what drives the unique adaptations.
