i have spoken too soon. i had my dev environment in php 8.0 which was generating another error. this is NOT a confirmed bug.

i have confirmed that changing the config value:

Payment-Block Action on Shipping Change
Key: CHECKOUT_ONE_PAYMENT_BLOCK_ACTION

to refresh solves the issue.

TitanOwl you are correct.

Balaji, your problem is now solved.

best.
