There are several different dates. Each state has their own deadline, but the federal Electoral Count Act specifies the "safe harbor" date for certification of EVs -- which is December 8, 2020.
A state can still certify EVs after that. But, if they meet the safe harbor deadline and follow their legal process, Congress cannot challenge it during the EV count in January.
If certified after the safe harbor date, a Congressman or Senator can submit a challenge. If the state doesn't follow a legal process, they can also challenge. Pennsylvania in particular could be interesting, as they ignored an order from SCOTUS prior to election day to segregate the ballots that arrived late. There are lots of legal questions in both PA and WI.
But, the challenge process probably won't help Trump. The House and Senate would vote separately whether to accept PA's EVs. Even presuming that Republicans would vote against it (a very narrow majority at the moment, and I think only one squishy RINO could block it), the tiebreaker vote would go to the PA (or WI) governor, and you can guess how that would turn out.
I'll reiterate that this is during the counting of EVs. This is a process that must be completed before it could be determined whether either Trump or Biden have a majority of EVs (and potentially put the election in the hands of Congress).
