Difficulties in initializing different GIS layers with ESRI

Hi to GIS community,

I am a GIS engineer and facing some difficulties in initializing different GIS layers with ESRI.

When I try to add different layers on a GIS map, I get the following error on my screen:

The error says:

Error occurred Error initializing layer: skd_hilir

I have searched a lot about how to get rid of the problem but still can't get to the root cause of the problem. If anyone can help me resolve the issue, I'll be really obliged.

Looking forward to an early reply.

Kindest regards
