Can't see tracked hands and controllers in my Unity Editor v62

Hello everyone! I'm currently working on a MR game on Unity, and at the moment I'm using the building blocks provided from Meta. For two weeks everything worked fine and I always was able to test my game directly on Unity's Editor, but by two days everytime I try to test my game directly on Unity I can't see my hands and controllers anymore! I even tried to launch old unity applications but even in that situation I can't see my hand even if I didn't touch anything from that project! Do you think this could be an issue from the latest building blocks updates or linked to the last Meta quest v62 update?
