This appears to be a classic case of overwatering. If the soil stays moist for more that two or three days at a time, then it is way too wet.

Make sure to let these dry out very well between watering. Since these were started in such a large container, there will be a lot of soil that stays wet for long periods. There are not enough roots to pull that water out, so it will sit in the soil, and likely cause rot.

I would only repot to what it needed to keep the seedling alive for a few weeks, and then transplant. This will prevent overwatering, and will allow the soil to dry out enough to prevent issues in the future.

This article will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/flowers/zinnia/growing-zinnia-flowers.htm
