Illustrator Crashing on iPad

I have an 8th generation iPad with iOS 15.3 installed. I have plenty of storage capacity and RAM. When I used Adobe Illustrator, the application crashes. When I draw with an Apple Pencil on the screen for a long time, the application closes itself. The application seems to work fine if I use short pencil strokes or save after each line I draw. What can I do to get this issue resolved?
