Sharpener 4.0 issues

Hi all. Yesterday I downloaded sharpen 4.0 and I’m having some issues I have a brand new 14 inch MacBook Pro with the M1 pro chip. When I open sharpener from lightroom to edit a photo a bar pops up that says downloading model file. This process can take anywhere from 10 to 15 minutes for a 66 MB file. I’m working off a high-speed external SSD hard drive that is plugged directly into the MacBook. If I wait out the bar to load, the program doesn’t do anything and if I try to change sharpen modes the same down loading model file box appears. I’m not sure why this is happening as I follow the steps precisely to install this new download. Can someone help me please?
