Why is F1 2019 telling me to buy the game? But i already bought it DXDiag

[K33N 0]

1.       The game tells me to buy the game in order to play again (i already own the game), when trying to reinstall it, it was just gone (this was on steam)
2.       The latest version (i believe)
3.       No gamemodes, just the whole game
4.       I was not able to recreate the issue
5.       This was a One Time issue
6.       No, since there was no option to verify game files.
7.       No
8.       There is no picture Unfortunately

DXDiag

I bought F1 2019 about 6 months ago, when i tried playing it kept on sending me to the store page, when i relogged to steam it says "purchase" even though i had already bought the game prior to this. so when i tried to reinstall the game, its gone. Can anyone help me???
