Stag beetle wing stuck

[aes]

My R. crenatus suddenly became extremely sluggish and unresponsive. When I inspected him, he had a piece of his wing stuck between his elytra and his antennae were tucked in.

As of now, his antennae are out, but he still doesn't respond to me touching them or his palps. He's also always rubbing his hind legs together and rubbing his back.

I'm assuming he might've gotten some substrate stuck under his elytra too, but I'm worried he'll be too tired to fly to fix his wings. Is there anything I can do or is he on his way out? I got him 2/3 weeks ago.

Was this after emerging?

No, I got him as an adult. His wings have always tucked in properly.

Sadly he passed just last night. Wouldn't eat either when I dabbed honey on his tongue or food.

Could it have been exhaustion that wore him out?

Could have been. Was he flipped when you found him?

No, he was all normal. I took him out to inspect him because he was acting sluggish and weird, and that's when I noticed his wing tip stuck.
