The crash log shows an EXC_BAD_ACCESS (segmentation fault) in thread 0 on the main thread, pointing to a memory corruption bug tied specifically to the Day View layout engine during print generation. Because week and month views work, the issue stems from a corrupted layout cache or a problematic single-day event entry.

Immediate Workarounds

Print via Week View: Switch your view to Week, choose File > Print, and adjust the date range or layout settings to isolate the specific single day instead of using the native Day view.
Export as PDF: Try choosing File > Export > Export... to back up the calendar, or print to PDF using a different view layout.
