If everyone is reliving the same day over and over again most people can go a day without eating with some mild discomfort, pretty much all agriculture, grocery, etc would become luxury and less needed or used.
All travel would become short distance you can’t spend 24hrs traveling to the other side of the planet just to get reset back home. Markets would go into stasis and stay closed there’s no interest earned over 0 days, which means most people would stop working as most jobs wouldn’t be necessary if everything just resets after 24 hours, you can’t build or destroy anything permanent.
I think most people would panic or just vacation for a few months worth of repeated days before organizing around new myths and practices and traditions around what caused it and how to change it back.
Seems a bit dry
