After updating from Mac OS Catalina to Big Sur 11.0 there were no issues with Starry Night Pro Plus 8, until I updated to Big Sur 11.1. There is an issue with shaders after updating from Big Sur 11.0 to 11.1. See error message below from screen shot after launching Starry Night Pro Plus 8:
Hope this can be resolved soon. There is no way to revert back to Big Sur 11.0.
