I am using Version: 8.1.32 restored the .gwbk File. I Can't open any view. Getting error like
"ExecutionException: java.lang.Exception: Unable to get the view config: View config is undefined. caused by Exception: Unable to get the view config: View config is undefined. "
Are you able to open the Perspective views from this project on a different machine? How are you launching the Designer? Remotely or locally? Can you try clearing out the .ignition cache folder and restart the Designer to see if that resolves the issue?
If you're still running into issues after clearing the cache, it would be a good idea to open a Support ticket with Inductive Automation so that this can be thoroughly investigated:
