Hi @capetom,
Some people were reporting crashing when updating to Sequoia 15. We released RW Classic 9.3 (which brought official support for Sequoia), 9.3.1, and finally 9.3.2 in quick succession to address some of those reports, as announced here RapidWeaver Classic 9.3.2 is now available
Try restarting your Mac as a first step. If it’s a Stacks issue after the most recent Stacks update, if you are still seeing a crash on a specific project, send over the crash report to us when the app prompts you so we can take a look.
@Pegasus Did you update to the latest Stacks version as well? Can you send in those crash reports too?
