AME renders 100%, but fails and shuts down before finishing

Hi,

I've created a project in PPro (Beta) v25.2.0 build 117. All my sequences, except one, renders H264 and completes using AME (Beta) 25.2.0 build 117. This sequence renders 100% , but fails to compile the finished file (Audio/aac and video/m4v). It just shuts down AME (Beta) and when I re-open the program the render que has reset and is ready to start again like nothing happened.

Prosessor Intel(R) Xeon(R) w7-2495X 2.50 GHz
Installed RAM 192 GB
Systemtype 64-bit OS

Nvidia RTX 4500 Ada Gen driver 553.50

PS The sequence renders just fine in PPro (Beta).

Thanks for any help
