Beta version now crashing after Midjiwan logo?

Anyone else on the Beta branch finding this has started happening?

I've been really enjoying doing the weekly challenge each day for the past couple of weeks, but starting yesterday I've been unable to launch the Beta version of the game - as it crashes right after the Midjiwan logo appears.

I've restarted my pc, closed Steam and reopened, installed the regular branch of the game and launched that with no issue, reinstalled the branch, same issue.

:(
