Hi @Kishan Belel,
Thanks for your detailed explanation, I am more than willing to help you out.
However, the problem you meet is unrelated to the product we are responsible for. Our team is mainly in charge of SharePoint. However, Project Web App is part of Microsoft Project, and we lacked knowledge and information about this product.
For the issue you mentioned, it would be more advisable to post your question in these two communities to get professional support in time.
