As the title already says since the last friday update to Solus Rapid Photo Downloader does not start anymore. I attached the corresponding logs to this post. Does anyone know a solution to this? Sadly the program is an integral part of my post processing workflow.

Help would be very much appreciated! Thank you 😄
