Flashing Log-in Screen And Logonui.exe Error

Since this morning when BitDefender was updated, I have been getting a flashing log-in screen whenever I lock my PC or I wake it from sleep mode. I have to force my computer to shutdown. I have no problems booting my PC but whenever I restart or shutdown I get this error: LogonUI.exe application error, The instruction at 0x.... referenced memory at 0x.... The memory could not be written. Click OK to terminate the program.


It seems I'm not the only one experiencing this issue.

Is there a solution to this problem? I am getting very frustrated.
