Error while launching open Studio ESB 6.3.1

[anna_talend]

Hi,

I have been working with Talend Open Studio ESB 6.3.1 on windows for about two years and stopped with my project in December 2019. Until this time everything was fine. Now I tried to open the studio again and it fails while initialization of the generator engine. It just shows a message: NullPointerException and nothing works anymore.

I have no idea what could have changed.

Even with a new created empty project I get this error.

What can I do?

Best regards
