Simulacrum crash

Was doing level 3 Simulacrum adn the game crashed. When trying to reconnect on that character, It loads for a while and eventually goes back to home screen saying "Disconnected: Failed to connect to instance".

It was maybe wave 8/9?

Have tried a few times, and same issue. I cant log into the character at all. Please let me know asap if there is a way to get into my character and play.
