I think this is what's happening -


Basically, the backup camera has lost its initialization and needs to be re-initialized.

One other possible solution before attempting the full on Service Mode method perfectly
performed in post #9 is to simply run start the car and put it in Reverse. Turn the steering
wheel from Lock to Lock a couple of times, pausing at each extreme for a second.

yep. That is often all is required.

For future reference, mcomer's suggested solution is found in the LEXUS 20XX ES300H, ES350 NAVIGATION AND MULTIMEDIA OWNER'S MANUAL (on page 196 of the 2021 pdf version [page number varies by model year]) in the "7-1. Lexus parking assist monitor" sub-chapter in the "If you notice any symptoms" section.

Confusingly, the same exclamation point in diamond symptom is also found in the the " 7-2. Panoramic view monitor" sub-chapter with the same "Likely cause"listed but the only solution listed there is "Have the vehicle inspected by your Lexus dealer."
