Rush keeps on crashing (usually after I add an image to a video)

I have abatnd new laptop (with Ryzen 7, 16GB Ram, multicore etc etc.....) but since I installed Rush on it yesterday I´ve barely been able to work with it for more than 5 minutes. I need to add images to my videos but almost every time I do, the programme starts to freeze. Instead of showing the image with the soundtrack underneath, it will usually show a frozen image of the original video instead. Even when i then try to play another, seperate part of the clip, these begin to freeze, too. Based on the sheer number of complaints from users, i´m getting a little worried that this was an expensive mistake
