Fenix 7 Pro software 17.20 stable continuous crashes

I upgraded my Fenix 7 Pro to the stable version 17.20 via OTA tonight.
Subsequently, the device began to restart repeatedly, prompting for re-pairing with the mobile phone;
even after performing a hard reset and reinstalling the software.

Attempts to initiate the OTA update check also caused the Fenix to freeze, and it was not possible to shut down the device from the menu.
To revert to a stable state, I had to downgrade to version 16.22. Despite trying the OTA update once more, the issue persisted.
Consequently, I am currently constrained to remain on version 16.22.

Today I made another attempt with the same result, also avoiding reloading the backup and connecting it to the smartphone.
Seems "stable" only with wifi and bluetooth disabled.
I had to go back to 16.22 again disabling automatic updates.
