Installed application through app store, when I go to select what type of screenshot to capture from the toolbar menu, or using a hotkey, the application silently crashes with the default settings.
I see in the console that there are some log lines relating to some exceptions, but there's not a whole lot of detail.
Let me know what else I can provide to help you (or where the crash report is located on MacOS!)
Greenshot Version 1.2.9 from App Store
