My game was immediately crashing upon attempting to bring up the build menu (up on the d-pad) suddenly, while having no issue earlier.
Turns out if you have way too many unique bones in an accessible place for the build menu to pull from, it doesn’t like to suddenly have to populate a menu with 60+ unique skulls.
Which is why it was just crashing instantly.
I shoved all the skulls I’d been collecting the last few days into my colossus (I knew it would have a use some day) and then switched exocraft so it was no longer the primary one.
Can successfully build again.
Thought I’d make this post in case anyone runs into the same issue on PS5 or other platforms.
Sent a video of the crash with explanation of the reason and the remedy via ps5’s auto-crash report thingy (it happened so many times, by the third report I deduced the cause and typed it in the info pane)
