Exception has been thrown by the target of an invocation

Hello,

I am new to Trados and have been using SDL Trados 2019 Studio since September 2018.

It worked perfectly fine for a fortnight but for last 2 weeks, I am getting the error "Exception has been thrown by the target of an invocation" as soon as I open the studio and then it closes down. So, I have not been able to see even the translated files or files for which translation was in progress.

More details about the environment.

OS: Windows 10 Pro

Office: MS Office 2007

PC RAM: 4 GB

Processor: i3 6th Gen

PC: Lenovo

 

Could you please help me out.

Thanks a lot.
