After updating postman to the latest version (10.12.1) in all my collections, all requests became with an empty url and empty parameters

My question:
How to restore all my requests?

I had some old version of Postman, I periodically added collections, added numerous requests to them, in which the url and various parameters were specified.

All this worked fine until today, when I wanted to update Postman. After the update, I still see all my collections and all requests in them, then none of these requests can be executed - they have an empty url, empty parameters and default headers. Where did everything go?
