Yeah I would say it is dying. Maybe it got cooked in the sun and then you didn't notice until after the rain. Probably roots got cooked. Is that a clay oven it is in? Any additional info could help you get a better answer.
That plant is 83 days old?
It looks like there’s new growth that might pull through. Let the soil dry out and give her a chance. These girls are incredibly resistant! Curious where you’re at and if there was wildfire ash on it before the rain?
