Migrate site from local to local via a backup

I have a WordPress site installed locally on my computer. The project was almost finished. Today I turned on my computer but it no longer works (categorically refusing to turn on), the repairman told me it’s hard drive problem but I managed to get the project files which was in this hard drive thanks to a file recovery box (I recovered the WordPress files which were in www).

Before that, I had made a backup of the project in Dropbox via the UpdraftPlus plugin.

Now I bought a new computer and would like to know if there is a way to get my project back and how.

I count on you if not I will lose two months of work. Thank you in advance for your answers.
