Hi @Shakthi1 ,
1. Go to /system/console/bundles
2. Search for bundle com.adobe.granite.crx-explorer
3. Stop the bundle and it will turn to a resolved state.
4. and check https://hostname/ crx/explorer/browser/index.jsp
@Shakthi1 Basically it is a mix of other replies posted here.
You want to restrict this for particular users or user groups? Also do you want to restrict access on dispatcher level?
However, if you want to restrict users from CRXDE based on user permissions, you can utilise Sling filters like this, https://aemlab.blogspot.com/2020/04/aem-crxde-restriction.html
