Startup hang (beachball) on macos with 1.0.3

Steps to reproduce

On both macs in our house (One Monterey, one Catalina, different vaults), obsidian now endlessly beachballs on startup. Tried reinstalling. Tried blowing away all .obsidian files. No Joy.

At least one of these uses iCloud sync (don’t have the other in front of me to check)

Any advice on how to troubleshoot this one?
