I encountered the same error, and it only appears on a specific place I am working on with team create enabled and another developer editing the place.
To add to the above post, if you are still seeing this error please include a fresh screenshot of the error dialog. The one from the OP unfortunately happened while the error message was broken so it just shows ‘%2’ instead of the error code.
This has since been corrected so any new screenshot should have a more detailed error we can do something about.
