On Steam you can do this:
Right click the game in the steam client, click the "properties" option, click the local files tab, select "verify the integrity of game file"
Then it should restore the correct files
On Epic Games you can do this:
Click the "..." option below the games box art, click verify
That will restore the original files
If you have it through Rockstar directly, I don't know, they may not even have that and you may have to do a full reinstall
