Game crashes on entering hideout

Last week I spent a few hours creating a new hideout design in my Celestial Nebula hideout but since the new update I haven't been able to access it.
The load screen will appear but then the cogs at the bottom of the loading screen will freeze and the game will crash to the desktop.

I have tried verifying the files, reinstalling the game and also using a different renderer but to no avail. I've used Helena to switch to a different hideout temporarily but I would really like to use the Celestial Nebula.

Any help would be appreciated.
