Capture one doesn't work properly

When I shoot on a tethering, every picture appears blurry. Only when I zoom in do I see the image sharply. The display is not comfortable. It is also not possible to rotate the images, or cut them easily.
It seems that the software have a problem and I can't understand why this is happening.
It happens to me even when I'm not tethering.
In addition, a feature that does not work at all is the advanced color editor. It just won't pick any color I choose, which make my work not easy at all.
I tried to update a version of the Mac, currently on sonoma 14.2.1. I also tried deleting the capture one app and reinstalling, and it still didn't fix the problem.
I need a solution, I don't know what to do and who to turn to because capture one doesn't exactly make life easy turning to help and support, I only managed to get to this forum.
