Failed to load map! .umap appears to be an asset file after sudden shutdown

Hello! good afternoon everyone,
So i’m eating up my lunch while my laptop is opening Unreal Engine 4.25 because i’m in the middle of doing my work on unreal so i don’t shut it down, but suddenly my laptop bringing a loud noise and then after a couple of sec my laptop was shutted off.

After that, when i try to turn on my laptop again and open up my unreal project, theres a warning says “Failed to load map! .umap appears to be an asset file” and after i close the popup, my maps turn all black, theres nothing on it.

I’ve tried to look the answers on the forum, i try to change the default map in the project settings and I realized that theres no startup.umap on the list, but theres untitled.umap which is all black when i open up.

How am I supposed to do? I’m really confused right now because i really need that file and don’t know what to do to recover it up.

My laptop spec is:

MSI GS75 Stealth 10SGS

NVIDIA Geforce RTX 2080 super with Max-Q Design

32 GB RAM

Intel Core i9-10980HK @2.40GHz (16 CPUs)), ~3.1GHz
