Macos App Is Damaged And Can't Be Opened

  

So I was downloading Xbox 360 controller drivers and then it asked me to restart my mac, then i when i log in my computer functions as normal but some applications show this message: 'can not open application because it may be damaged or incomplete', my first instinct was to restart my computer but it only made it worse happening to ALL my finder applications and files. Please Help my mac is unusable at this point!!!!

Thanks for the reply, I ended doing a clean installed of the system and apps, then I moved my files manually. It worked perfectly and my Mac was running like new until yesterday that I did the Mac OS 10.15.2 update, now all the files on all the accounts in the computer are '.'is damaged and can’t be opened. After clicking on 'Open Anyway' in the above screen: Click Open in the above screen and Synology Assistant will be opened. root cause Starting from macOS 10.15 Catalina, apps are required to be 'notarized' by Apple. This is an additional signing step that needs to be applied on the apps before they are released.
