Sudden error on Unity OVR Build and Run APK

Working on a game in the App Lab in Unity for months and never had an issue before when  uploading to my Quest.

Haven't changed/updated/whatever and now when I hit the OVR Build APK and Run

It builds the apk and gets up to Installing APK but then gives this error:

OVRADBTool avc:  denied  { read } for  scontext=u:r:system_server:s0 tcontext=u:object_r:sdcardfs:s0 tclass=file permissive=0

I tried the solution from huebreeze - https://forums.oculusvr.com/t5/Unity-Development/Quest-2-Unity-Issue-with-OVR-Scene-Quick-Preview/td-p/834719/page/2 but no go (code is on different line)

Any help would be appreciated. Can't advance without be able to run.

Thanks
