Welcome to the Serif Affinity forums, @tammy 4 life.

Yes, loading many LUTs (how many did you load?) can cause a slow-down, but that should happen only when you're looking at the LUT Adjustment in the Adjustments studio panel. At that point Affinity Photo needs to generate a preview for each of the LUTs you've loaded, which will be a CPU-intensive operation that will take a while to complete.

Hey tammy 4 life,

How many LUTs are you talking about?

I have loaded 100 before and when switching to the Adjustment Panel to display the LUTs, it took upwards of 2 minutes to get a response from the app and is expected—as Walt suggested. 

If you've waited more than a few minutes and believe the app has locked up/frozen, it might be worth getting a Windows dump file from Task Manager... but I would wait a good 5 or 10 mins or so to make sure the app has given up.
