Unable to add new records - have an infinitely spinning icon

Good Morning

I am unable to add new records. Below is a screen shot with data blurred for privacy. The date has a infinitely spinning icon as well as a lookup field. The next field is a filtered lookup that remains unpopulated. I am experiencing this on multiple applications that worked fine last week. Please advise.



Thanks for you assitance.
