Did you do the previous updates over the air, or usb stick?

When I started the car (UX250h 2021) the navigation system went straight to the round wheel on the screen that indicated it was doing an update. I left the car on for over 4 hours and nothing happened other than the wheel kept turning. So that was aborted and I downloaded the v2 for 2023. I have done this before and the latest version downloaded to the USB. However on loading the USB to the system it would not accept the USB. I checked the status of the nav system and saw it had reverted to 2020 v1 (the default) and there was no history. My local garage is having the car in next week and Lexus HO technical are aware. A recall of this model was performed in September and I don't know if that caused the problem. Lexus computer software is not that good.
