Losing a collection after updating Postman to v7.0.6

The version is 7.6.0
Mac system
I lost a collection today when I used other collections.
I checked the trash but it was empty https://web.postman.co/me/trash

Https://web.postman.co/me/collections?view=all empty too
This collection is very important to me, ask for help
