Welcome to our community, CN Writer
Where is the project? Local C drive or a network resource? I
ask because it's quite common for all sorts of issues to erupt if
you are working on your project while it is stored on a network
resource. And if that's the case, this could be the cause of your
woes.
You should always work on your project only while it is on a
local storage such as C or an externally attached hard drive.
