Unity failed to decompress package

Hello, unity community. I am trying to import unity ads to my game and I get an error(I will put the error in a code format so it looks a bit better)

Failed to import package with error: Couldn't decompress package

I looked into the editor log and found this:

Any help would be greatly appreciated.

Also, I tried changing the file location however that only made it worse with far more errors so I put it back.
This is unity 5.

Bump. Please help I can’t really do anything in unity, can’t import ANY unity packages.
