Lost my Engine setting

I’m using engine version 4.20.3 . For some reason my pc stutdown so after restart my pc again and open my project .i lost my engine setting every set to default mode. My collission presets objext every. why i lost my settings ???

I don’t know why because your engine settings are saved automatically. But if they take a long time to set up, I suggest that next time you export your settings to an ini file. There is an Export button in the Project Settings.

Thanks dear.
