It seems to have temporarily resolved, although not optimally.
I realized that a new version of OpenXR had come out, which I updated from the Microsoft store. Furthermore, the new version of SteamVR Beta has solved the various crash problems caused by the dialogue with OpenXR.
Updated everything, I set SteamVR as the default application for virtual reality, replacing it with the Oculus one.
I have yet to find the ideal setting between sharpness and fluidity, but what matters is that the motion tracking now works correctly.
