Game breaking bug (broken base leyout in defence mission)

So i recently started my second playthrough on PS5 and stumbled on game breaking bug. Basically during base defence mission the base layout is broken and entrance is completely blocked making it impossible to complete the mission and progress any further. You can see what i’m talkimg about in the video i posted on YouTube. Please fix ASAP
