UQ Dark Falz Luther(The Boss himself post 30minutes) Keeps crashing me after jumping down from Gateship

So I'm a player playing PC version of the game, it's just weird that I could run alot of Apos Dorious Mini Boss runs, and do everything else normally fine, and then when the timer ran out, and we can face Luther Boss, I entered Gateship and then jump into telepool and then the game loads for a second and then the whole game crashes without any error messages. Any Devs or anyone who experienced this can I ask for any possible fix?
