I have created the sharepoint trial account and i tried to activate "SharePoint Server Publishing Infrastructure" feature in site collection features.But i got error with Correlation id.How can i debug using Correlation id without any powershell scripts?

Just as Ganesh said, you will need to open a service request with your Correlation ID to further troubleshoot.
For the feature issue, What is the template of the site collection having this issue? Can you reproduce the error in your other site collections?
Is the site collection in Modern or Classic experience? You are unable to do this for various reasons. More information will be helpful for further troubleshooting.
