I think I might have completely softlocked my party... any ideas?

So, I was crossing the desert with my Mk2 bike on my way to a mission at 3500m when I realized you cannot go over quicksand. My beloved Mk2 bike? Boom. Gone.

Whatever, I think, I’ll hoof it back to where I died and grab my gear. I manage to recover my stock and start heading back to base... and then, of course, I get eaten by the worm. Yep, all my freshly farmed and crafted weapons and gear — wiped in an instant.

Frustrated but not broken, I respawn and teleport to my base... only to realize I'm now stuck under it — inside my own stronghold, which apparently is buried beneath the base structure. I'm completely naked, no tools, no resources, no construction tool to get myself out. I'm trapped in a 15m² coffin with no way out.

I’ve sent a ticket to support, but right now I’m literally softlocked. No gear, no exits, no way to rebuild or craft anything.
Did I just permanently screw up my save?

Has anyone been in a similar situation and found a workaround?

Or I'll stay here forever.
