It is the wrongest of all the wrong possibilities.
The TinyDB component dies when you cross screens (though the database file is still there if the new screen were to contain its own TinyDB component with the same NameSpace.)
To fix it, add a TinyDB1 to screen ScoreDB, decide on a tag in TinyDB like 'scores' for your scores, and store the scores there in the first screen for the second screen to look them up when the second screen needs them.
Don't bother passing anything as start value, just use common TinyDB tags.
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
The Elements property of a listpicker or listview is only able to accept lists... you are trying to assign the string "not found", which obviously will not work

but now how to print the answer choices as it only takes up "or if not found" value
