There are two different groups of people and two different deceptions being discussed by Paul in the 2 Thes 2:1-12 passage.
The first group is the Church of the Thessalonians of 51-52 AD
The first deception is the idea that Christ's presence had already returned.
Note: There is no need to warn them about this if Christ's presence would be thousands of years from then.
The second group are the 1.1 million Jews who perished in Jerusalem from 66-70 AD.
The second deception was the idea that their king, Caesar, came to liberate them from the 3 tyrants who were killing and abusing them.
