It looks like there is an issue with the layers DWR_Habitat_Layers_Service, Geology 100k (30X60 Quads), PLSS_Service and Sage Grouse Management Area (SGMA) as they cannot be added to the map.
You say that everything worked fine until two days ago. So, it seems that two days ago something has happened that caused these issues. What could that be?
By the way: two days ago, on the 19th of March 2019, ArcGIS Online has been updated: What's new in ArcGIS Online (March 2019)
Might this have caused the problem?
This is the error message that appears on my screen just before the systems asks me to login to Utah DNR Online Maps:
