Why do election officials need to get election results early?

Early and continuous vote uploading and reporting is counterproductive to the goal of safe and secure elections. Too many potential attack vectors and bad actors could obtain that information, and the risk-reward ratio doesn’t make sense.
The only reason for that is to cheat and potentially call-in last-minute voters. This undermines the trust of the voters and must be addressed. There must be no vote totaling until the polls close. County employees would know the local results and would be reporting these to the Election commission via the ENR computer (which is connected to the internet). There is no reason why the election director or board of elections should have that information early. That is a severe risk and one that could be easily compromised.
