@Debsoh i found this for you:?
If you're experiencing the "The application was unable to start correctly (0xc0000142). Click OK to close the application, Untrusted system file: Windows\System32\dbgcore.dll" or other "Untrusted system file" errors, it indicates that a system DLL is blocked from loading because it was detected to have been modified. This means that the original system DLL contains some foreign injected code that cannot be allowed into the game process memory space. To resolve the system DLL related errors, use Windows Update. An update to the latest Windows version should resolve the issue.
check running background programs !
