### Apache NetBeans version
Apache NetBeans 13
### What happened
I created a web application project, the first time working with it was
fine, then I close netbeans and tried to load it up again but this time, the
project tree is not showing up at all, and I got an error/exception:
java.lang.NullPointerException: Cannot invoke
"java.nio.file.Path.startsWith(java.nio.file.Path)" because "path" is null
