I am getting the exact same error on iOS 14.2 (beta 1), by coincidence trying to load the exact same image:
Image("checkmark.circle.fill")
.renderingMode(.original)
It is crashing with other multicolour SF Symbols as well. It must be a bug, and is not under the known issues in the beta release notes. Have filed under FB8725305
