Can’t do anything it just says "Model loaded 0s (0.0fps) for unlimited time.
can’t preview, can export, tried reinstalling, tried different outputs and different combinations of enhancements.
Old version where you can only use upscale works though…
MacOS Monterey 12.7
MacBook Pro (Retina, 15-inch, Mid 2015)

You need to buy a new Mac. (sorry, I don’t intend to be rude)
Older hardware is not supported by newer versions of MacOS, and many features implemented in newer creative software depend on newer MacOS features. That’s why the old software works better for you.
Your Mac isn’t even supported by Apple anymore (which is why you’re not on MacOS Sonoma 14.0). Their hardware support typically expires about six years after the initial release date of your machine (support ended in 2021 in your case).
