While trying to open a already saved PBIX file getting the error :- Object reference not set to an instance of an object. I'm not even able to open the file. I have lot of work in it.. How will I retrieve my file. Any help is greatly appreciated. This is bad from a tool perspective loosing all the work suddently. Atleast I should be able to open the file and deal with the error.. My source is snowflake. Again any help will be greatly appreciated.
