hi @Engineers  
There was a similar error ““Ambiguous identifier” in the log  
The original error had to do with a symbolic link  
One Drive does not support symbolic links,

> As of the 31.00 Update, Asset.digest.verse was giving me thousands of errors due to having a folder in my files titled “FNSG” while the project and verse path was also titled “FNSG” This was never an issue before 31.00. It gives me this error:

> “Ambiguous identifier; could be denni@fortnite.com.FNSG.FNSG or denni@fortnite.com.FNSG”

> Fix: Renaming the affected Folder, updating the redirectors, and deleting old folder.

> Just giving extra context incase any of these extra errors have anything to do with the main HUD message device versus error!
