Since you get 500 Internal server error, something should show up in your error logs. Did you check this?

Right click this URL, open in new tab, read full error message?

This is the actual error I am getting -

Unable to load /EPiServer/cms/Stores/contentstructure/?referenceId=68&query=getchildren&typeIdentifiers=episerver.core.pagedata&allLanguages=true&sort()&dojo.preventCache=1648053497736 status: 500

68 is the id of my main page, the content tree under which is not loading.
