It is an Apple pre load app. I tried to share it here but it wouldn’t copy and I couldn’t find it in the App Store. Try this link https://feedbackassistant.apple.com/

Same issue on an iPhone 13pro which just updated to iOS 18.7.2 a couple days ago. No issues before the iOS update.

Phone updated to iOS 18.7.2 the other night and I have lost all animations and colors on my map. Gray map still gives data, but it’s hard to track and plan without being able to see the graphic movement. 13 errors in the debug log on an iPhone 13pro:
Here is one of 13:
