EDIT: On further use of RStudio my solution didn’t solve it – The sync popup just occurs at a lower frequency. The problem is that Google Drive currently doesn’t have a feature to ignore Folders just filetypes.

This solved it for me:
- In Google Drive/Backup and Sync go to Preferences…
- Under My Computer click Change:
- Under Ignore files with these extensions add
.rproj.user
See screenshots below:
