Forum undhandled exception error VVVV 2021.4.0-150


its quite hard to explain that issue.
I added a quad renderer, just translated and scaled it, then suddenly VVVV crashed. afterwards i was not able to open my project any more.

I always got this error message.

I tried to reproduce what i did with a backup version but what i did before worked without any problems.
Maybe someone has an idea what this error message means and what happend?

You should post broken patch
