I’ve installed yay -S mongodb-bin… it installed successfully but not work! 
even, when I try to start mongo.service with sudo systemctl start mongodb it fails!
I’ve searched a lot on google… everyone just suggest this way yay -S mongodb-bin.
I did the same way but not work for me!
how to properly install & configure mongodb?
Use mongosh instead mongo
It would be preferable to post the terminal output as text and not as screenshot.
That way, it would be easier to copy, paste, quote and it will be searchable by forum’s search function and other search engines.
Open a terminal in full size. Run your command. Copy and paste the output as text, highlight it and press Ctrl-E to format for better readability.

I am not using mongodb so I might not be able to be of much help to you.
However, you might want to examine the coredump and see if it will give you some clues on what might be wrong.
Could be down to your using the -bin package. Try the standard mongodb package instead.
But also, there’s a section on “MongoDB doesn’t start” on the wiki page already linked.
People in the comments of mongodb-bin AUR page complain that Mongo 5 does not work on older processors, hence core dumps. You might also try an older version of Mongo like mongodb44-bin.
That might not be a problem if it’s compiled from source using an older CPU, as the compiler will use the correct instructions for the CPU. However, if the MongoDB developers have used microarchitecture-specific instructions (e.g. anything part of SSE4.2) then the only option is to use an older version of the software.
