Disney's announcement came a day after performers claimed the show had been permanently closed.
The "Dark Arts at Hogwarts Castle" projection will run nightly at Universal's Islands of Adventure starting Sept. 18.
The 2021 event will be called Disney's Very Merriest After Hours.
The announcement comes off after months of relative silence about new offerings for Disney World's 50th birthday.
Each Disney World theme park has now passed at least two COVID-19 inspections from Orange County "strike teams."
The show hasn't run since Disney World reopened in July.
The unannounced visits determine whether theme parks are complying with Orange County, Florida's rules on face masks and physical distancing.
The open jobs include positions for which SeaWorld had recently permanently laid off furloughed employees.
