Strong sweetish odor

Hi. Please help. I have searched the internet and could not find my exact question posted. First time in an rv. Rv toilet had the very faint typical rv sewage smell when we started trip 2 days ago. Today my wife “had to hold the flush valve open and let it run for a really long time” ;)
But now there is a disgusting, sort of sweet smell, not quite like anti freeze, coming from the toilet and is permeating if I turn vent off.
Does anyone know what this odor may be and what I can do to kill it?
Thanks for any help!
