Keeps crashing! – Thumbnail Maker for YT Studio Review

At first this was a great and fun way to make thumbnails. Now whenever I open the app it crashes. I've deleted it and re-installed it many times, but it keeps crashing. This is very frustrating. It's was 5 stars but now it's 3 stars. I'd make it 0-2 but it was fun at first and I did enjoy it.
