Retrieve local file after overriding it with cloud one

I got a conflict error (see https://www.insynchq.com/i/features/conflicts-resolution) for a single org file and I decided to keep to cloud one, as I worked yesterday from my laptop. Unfortunately, I just realized that that filed had failed to upload to the cloud since 24/07 despite I am working with it every day, due to an “access token expired” error that I am getting for a number of files and insync team is already informed but haven’t done anything yet.

Is it possible somehow to retrieve my old local file? Otherwise I would miss the work of a whole month!!!
