Magento 2.3.2 with Magento-Braintree Payment

[bst2002git]

The checkout fails while in the cart-quote "reserved_order_id" is missing.
Can someone help?

After deactivating CleanCheckout and using Magento default Checkout Magento-Braintree-Payment works.
Sometimes it with CleanCheckout activated it goes one "step" in process forward and i get the Error to check my (correct!) Shipping/Billing Addr.
