raise Exception(f"Chunk {chunk_start} to {index} exceeds the chunk end time {chunk_end_time:.2f} seconds with current time {cur_time:.2f} seconds") 最后合成的时候出现这个错误是什么原因呢？

Start with core/step10_gen_audio.py, especially merge_chunks() around line 209 and gen_audio() around line 231, then trace the tasks_df timing values that produce the reported exception during final audio merging. Reproduce the failure with the reported workflow and identify why current time passes the chunk end time; done means the reported input completes without this exception.
