I have installed the new OneDrive with group sync (version: 17.3.6642.0922). After syncing it gets is a kind of pause mode; no file syncing anylonger... Workaround is to stop syncing and start again.

I also have found the Onedrive preview version (the one that supports groups/sharepoint) to be very buggy, it frequently stalls at "Processing Changes" and never recovers. Same release as you, 6642.0922. Certainly not ready for prime time, hope they continue improving it quickly.
