Minecraft Bedrock is not working anymore?

I got free Minecraft Bedrock Edition for Java Edition for free some time ago. It always went very well until recently. The game could not be started and crashed immediately. So I wanted to install it again. I have now uninstalled it, but can't find it in my Microsoft Store Library anymore. How can I reinstall it?

Did you get an error code while crashing? If so, it would be very good for Pastebin.

Otherwise just contact the support!
