EXCEPTION at BR core Value cannot be null

When I open my project in AS4.1 the following fault shows up.

When click in accept B&R crashes. I have windows 11 but I can open many other projects, only this one is not working.

Hi @Ing_Bryan ,
Welcome to our B&R Community!
Unfortunately AS 4.1 is not supported with Windows 11.

Can you update your prj to AS 4.12.9? Otherwise I recommend to install AS 4.1 on the virtual machine

Ciao

Hello Valerio,

Thanks for the support, I will try to update or use a virtual machine.

Sad to hear its not supported for Windows 11

Best regards

I remember when AS 4.1. came to market Windows 10 was announced to be the last Windows version ever :slight_smile:
