Scrivener 3 keeps crashing

I have the latest Scrivener for mac, 3.5.2 running Tahoe on my macbook. This last week, it keeps crashing when I am copying or pasting something fairly small. And only once in a while. The only other apps open this time was mac mail, SpamSieve, and my browser (Comet). It’s getting scary just using Scrivener now, afraid I’ll lose something. Has anyone else had this issue lately?

All projects, or just this one?
