unable to load ai selection model

@Subrata31434404k14p there is a previous post with the same issue in Camera Raw where it was a lack of RAM causing the issue: https://community.adobe.com/t5/camera-raw-discussions/ai-selection-model-cannot-be-loaded/td-p/12887206

Go to Help menu/System info and copy and paste the report here.

In Preferences there is an option to set Select Subject to use local processing (faster) or cloud processing (more accurate). Change the value and see if this helps.
