New description:

 When using the following settings for hevc_nvenc:
 -tune 5
 -tf_level 4
 -lookahead_level 15
 The output file is reported as "isTruncated" in MediaInfo. The usual
 statistics(-stats) after the end of encoding are not displayed. It seems
 that shortly before it finishes encoding ffmpeg crashes silently. In the
 log file generated by -report the encoding appears incomplete.

 With -tf_level 0 , everything seems fine.

 The problem also exists in version ffmpeg-git-full 2024-04-15-git-
 5e380bcdb1.

 I'm on Windows 10 pro 22H2 OS build 19045.4291
 Nvidia RTX 3060Ti Founders Edition
 Driver 551.86
