Laravel project homepage loads perfectly. But other pages not

I have an issue with the inner pages. The homepage of the project works well. But when I click on the menu items which are dynamically generated by product categories, it prints ^ "ja" on every page.

The same project files are also stored in a dem folder under the parent directory. Homepage and other inner pages in this demo directory work well and every page loads completely.

The output from the parent directory is as shown.

Tried editing the file in the following directory shows some changes.

public_html/vendor/symfony/var-dumper/Dumper/HtmlDumper.php

Does anyone who faced the same situation ever, help me to solve the issue.
