Sounds like you have a large version of the poop pyramid going on. Someone left the black tank draining during use. Some form of pooper-mache.
Choose a good bacterial poop/paper cleaner and put that in the tank, fill it with water, let it set a few days, take it for sloshing drive to really stir it up and let it set a few days more. THEN dump it and wand it out.

Many swear by the ice cube trick. Best bet there is to make your own large solid cubes so they have chance to knock things around and apart before melting. But if the contents isn’t softened a bit before, it won’t work that well. Also when using ice cubes you don’t want a tank full of liquid. You want the cubes knocking around the bottom.
IF you have a direct drop into your black tank, you could lightly use a pressure washer to break the pyramid apart. The reason I say lightly is BACKSPRAY and high pressure water could eat into the tank plastic.
