My mac is using Catalina, I was following the link installing macOS Beta on a separate APFS volume - https://support.apple.com/en-us/HT208891 to install Big Sur Beta. After installation completed, I switch back to Catalina, I found the developer app installed on Catalina won't work, it crashes immediate when I open it. I tried to delete the volume that installed Big Sur Beta, but it's not working, I am still not able to open developer app. Further more, on Catalina OS Volume, there are two new volume was created: Volume with name update appears on desktop, I have no idea what it is. Volume with name disk1s7 appears on disk untilites, I cannot erase it, I cannot delete it. The question is, how to completed remove beta OS from separate APFS volume with the volume update and disk1s7?

I am trying to show a large text on Widget, larger than .largeTitle, and I notice when the text size exceed 48, the widget shows blank screen, and it come back when I change the text size to 47. struct TestView: View {     var body: some View { 				Text("Hi").font(.system(size: 48)) 		} } struct TestView_Previews: PreviewProvider {     static var previews: some View { 				TestView() 					.previewContext(WidgetPreviewContext(family: .systemSmall)) 		} } The Text seems stop expending itself. Is this the limitation or I missed something?
