My own experience is that Apple, Google and Microsoft Drives are at their best with their own programs. And I’ve had many irritations with all of them. OK for pure storage, but their syncs for other files can intrude. Box and Dropbox have to make it on their own and I’ve always found it a smoother experience. And reviewers seem to concur most of the time. But they all have their own idiosyncracies.
So Obsidian back up 2 seconds after you stop typing. Assuming that must have happened a few times, the Google sync can’t have been functioning correctly else there would be saved versions online.
Sync programs clashing with autosave can result in problems. A safer approach would be having the working files in a local only folder; using a local backup program to backup (one way only, not sync) that folder regularly (2 minutes, 5 minutes - whatever works best for you) into your Google Drive folder which then manages its own schedule for online sync.
