This crater appears to have been mostly filled with lava, but there is no vent apparent within the crater: could it be invasive lava? In the eastern part there are many rafted-looking blocks that may have eroded off the crater wall. They don’t have the texture of (geologically) fresh lava. Many of them appear surrounded by moats, suggesting that the lava crust was strong enough to partially support them.
