The syntax is

gvim -V20debug.txt

The name of the debug output file _immediately_ follows the debug
level. Take another look at

:help -V

and I think you'll see this.

You could single-step through the restoration process by prefixing
the restore command with ":debug" (see ":help :debug"), but that
could be really tedious.

I don't often save and restore sessions, so I probably can't offer
much useful guidance with that.
