Is it your base?
Or someone else’s?

If it’s someone else’s I don’t think there’s anything you can do except remove your bracelet. Then hopefully you have sorcery summon corpse spell to get your stuff back. You might have to cast it a few times. I had to when I was stuck in a someone else’s base.

It’s a known issue with chapter 4.

Maybe someone else can confirm there’s no other solution before you remove your bracelet.
