Team Asobi has rolled out the first post-release patch for Astro Bot and it's a small download which shows up as version 1.003.

Team Asobi has not released any patch notes yet, though we are hoping this title update will be to fix the crashing issues, and even a save issue that is plaguing players. It seems you have to exit via the dashboard to make a save, as doing otherwise leads to your progress not being saved (one ResetEra poster lost five hours of progress due to this).
