Hi @Veenakrishna,
Thanks for the additional details of the issue you’re seeing.
After checking the forums for similar issues, I found this past forum post. I believe the issue with the blank page is caused by this line:
"homepage": "https://veenakrishna2313.github.io/Portfolio-Website/",
within the package.json. Could you try removing that line, saving then redeploying to see if it resolves the issue?
