Please heIp, I was fiddling around with some platform xml to change the file extension of all games in Atari 5200 and Sega Mega Drive, somehow I broke something, I guess Launchbox didn't close properly, already did a backup resotre but not helping:

 

String '2022-09-18T17:18:21.a5276023+02:00' was not recognized as a valid DateTime.

Nevermind I had somehow modified a date string in the Atari 5200 xml, added .52 in it. Crazy it broke everything
