Solution 1

The task gets a pointer to the array objects, not a copy. So when you clear the array, the pointer leads to an empty array. You can pass a clone of the array, that will work:

runningTasks.Add(Task.Run(() => ProcessTagsValidationInsertion(tvlFileTracker, tempRemainderTags.Clone)));

Clone is a method, so you'll need to add the parentheses to the call:

tempRemainderTags.Clone()

It also returns object rather than a strongly-typed array, so you'd also need to add a typecast.
