What's wrong with my Solar Radiation process?

Hello,
I am using the Area Solar Radiation tool. But the process never ends (it's been running for 24 hours even though I tried it on a small area). I couldn't understand what the problem was.

Projections of my DEM and my Data Frame are WGS-1984. I used to earthexplorer USGS.
Is there a possibility that there is an error in the Dem data I downloaded?

Did you see

Area Solar Radiation (Spatial Analyst)—ArcGIS Pro | Documentation

Calculating insolation can be very time consuming, where the calculations for a large digital elevation model (DEM) can take several hours, and for a very large DEM, even days. You may wish to do some test runs with a coarser resolution or subset of your data to ensure the settings are correct before committing a run with the full-resolution data.
