The training progress is stuck at 93%.

The training progress is stuck at 93%. The "Train" is grayed, while "Merge Weights" and "Convert Model" are both green. What could be the cause of this problem? And how can it be resolved? There is a warning: "2025-05-07 17:05:47 [WARNING] chroma_utils.py:60 - Unknown embedding model: BAAI/bge-m3, defaulting to 1536 dimensions." Is this related to the issue?
