I lost most of a day's work, SU Pro 2024 crashed

Has anyone gotten this message before? (dug down to Library>App Support>SketchUp2024)

I was closing SUPro, I had two projects open, I was prompted with a message about “changes to review” on more than one project. I clicked save on the secondary project (which was only open as a reference). SketchUp then either… quit? Or closed? I’m not sure. I came back after a break and got a bug splat/reopen dialog, all of today’s work was gone. The last saved version on Time Machine (external drive) is the same time as this message, but is exactly where I started this morning.
