I've been working in Studio 2019 for a few months and everything was fine but recently I've been unable to export any Excel file. It first started with one project, I completed the translation but could not export due to "Object reference not set to an instance of an object" error, restarting or resaving the file did not help (I created the project myself from an Excel file from a client). I thought it was maybe a one-off ocurrence but now I can't export any Excel file, to be sure I've tried creating simple Excel files from scratch and working in them in Studio but the second I want to export I get the "Object reference not set to an instance of an object" error, which makes it impossible to work! I've updated Studio, MS Office and Windows, everything is current but still the problem remains, please help!
