Bug [Windows] - build failed for android with gradle build issue

I am kind of new to Unity, but I faced this issue while trying to build anything for Android. This project is empty (just a canvas, a button and a text) but I can't build it because of a 'gradle build failed'. In the console, the errors and warnings I saw were 'access denied' ; 'failed to download any source list'
here are the entire console after I failed a build.

I already tried to reinstall unity. Does someone know what I can do to fix this ?

 

Try accessing the folder containing the file that is showing an access denied error, and check its security settings by looking at its properties. Ensure that the folder is accessible to all users.

 

Thank you! that worked for the 6 first errors!
But I still have those errors (same that the last five I sent last time)

I also tried to do it in the file concerned by those errors but it didn't change anything.
Someone have an idea ?
