This issue happens due to PHP changes and now need to use "continue 2" withing "switch" case.

You need to changes the vendor\zendframework\zend-stdlib\src\ArrayObject.php at line #426

continue

to

continue 2

NOTE:

We must not changes the core file, but until the next M2 version fix this issue, we can change core file at our own.
