Confirm it's lagging a lot! Especially in Franchise mode, like mentioned in a previous response, when adjusting the price of merchandise and concession. Also, swapping players or substituting and having to do a call-up from the AHL is a chore because of how slow the menus are. I mean, it's slower than PS2 era NHL titles... on a PS5.
That video found on YouTube (link below) illustrate this. It's not in Franchise mode, but it represent the speed of most menus in NHL 24 on a PS5.
But since it's near August and the next game is scheduled in a couple months, I'm sure the problem won't be solved despite being pointed out on release.
