Currupt file

Hello, my Sims 4 game will not open due to a corrupt custom content file that I deleted. I tried to repair the game, do a one-by-one in a new folder. The file I need is nowhere to be found, and I really do not want to lose my game.  It's a file starting in " ._ ". I got redirected here, so I hope someone can please help me after trying all the troubleshooting steps I was sent.
