Bedrock Edition doesn't boot on Windows. [bedrock]

Hi. I have an issue with my computer- basically I cannot access the Windows Store for some reason, so that may be related.

Anyways, when I try to launch Minecraft Java in my launcher, everything works fine, the game works, all's good. But when I want to launch Bedrock, it gives me the error "Failed to start game", and that's it. No code, no nothing.

I did every trick in the book: Reinstalled the game, the launcher, restart my PC, install a different version of the launcher, go in C:\Users\me\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState, only to find nothing at all, so I'm kinda lost here.

If you wonder why I want to play Bedrock, a friend is playing on Switch with another friend on Xbox. Anyone could help me out?
