EDIT:
After some additional testing, these other Modern versions are also crashing with an identical crash report:

Basic Modern Cottage, Basic Modern Hotel, Basic Modern Restaurant, Basic Modern Juice Shop.

The Basic Modern Cinema and Fruit Stand do not crash.

Thank you for the detailed report.

That'll learn me from trusting my ports from fabric! 😢
