Intermittent freeze when rendering

When rendering timelines from Premier, AME will occasionallly stop rendering.  I can end the queue, duplicate the item, then start rendering again and it will usually complete.

This leaves an incomplete pair of files (.aac & .mp4) in the destination folder.

I can't delete those filels unless AME is closed, BUT when I go to close AME, it hangs and has to be force closed. 

Once closed those orphan  files can be deleted.

Log just says "encoding failed." No clue why.

Log shows 27 of these events since 9/16/25.
