Actually, it is not a crash. The program is telling us that something it
was asked to do cannot be accomplished. A function throws an exception,
nobody catches it, and the program ends due to an unhandled exception.

I think the user who is running the program does not have access rights
to open Administrator's directory. (The rest of my post assumes that it
is an access right issue.)

Maybe the exception is being thrown during the foreach iteration,
outside of your two try-catch blocks. I would try putting a try-catch
block around the entire foreach statement.
If that works and if skipping the problematic entries is an option, use
an explicit while (or for) loop so that you can catch it more precisely:
import std.stdio;
import std.file;
void main()
{
auto dirRange = dirEntries("/tmp/deneme", SpanMode.shallow);
while (!dirRange.empty) {
writeln(dirRange.front);
dirRange.popFront();
}
}
Now you can put a try-catch around individual range operations:
construction, empty, front, and popFront().
