AME starting from 14.5 till 15.0 beta failes when exporting.

Short description:

Source Material is mainly 4k and above from GoPro Hero 7-9.

This appears only when using Hardware encoding (NVIDIA lastest Studia driver).
Software encoding works but is due to the unacceptable Runtime not an Option.

Exporting the same project again the error is at a different timestamp.

The error appears always between 2 Clips.

unchecking the following setting in AME "Import sequences natively" allows me to export succesful but the runtime is longer, however not as long as with software encoding..
Checking the above item produces the error again. This is reproducable.

Hardware is AMD Ryzen 9 with NVididia 16xx 32GB Mermory and fast M2 SSD Drives.
OS is Windows 10 latest Version.
Any Ideas?
