DR Studio not loading

Hi,
Big problem: DR Sudio 17.1 (dongle Version) won't load projects, or create a new one. It starts to the open/create project site and then I get a blank Screen (see screenshot).When this happens, I can only force quit, I can navigate the menu bar, but nothing changes or opens. It started a few days after using DR Studio without trouble, I did not have this problem with the free Version of DR.
Anyone has the same problem?
I'm on a MBP 2016, Big Sur, log file and screenshot attached
