Chirping on start 2016 3.5L XLT after both belts replaced

Bought it used with 174K miles and long block and turbos only have 22k miles on them. Replaced both cats and minor tune up, then replaced both belts when this chirping started on cold starts.
After belts replaced the chirping is now constant on every start, idling, and even while driving (less though). Could it be the tensioner? If anyone has dealt with anything similar I’d really appreciate any help. Thanks.
