Issue with changing Appendix format

Question

I believe there are many questions on this topic already answered. However, I tried all of them, but none of them worked with me. Perhaps someone can help me find the issue.

Currently, my TOC looks like this:

But, instead of "A" in the appendix, I want it to say "Appendix", like this

I tried this solution using Appendix package: https://stackoverflow.com/questions/5690679/add-appendix-before-a-in-thesis-toc But it does not work, it hangs when I compile it. Below you can see my code and all the packages that I'm using. Maybe some of them are conflicting.

Use \usepackage[titletoc]{appendix} and then use appendices environment will do the result.

Hopes this helps
