Whisper large-v3 finetuning

I’m trying to finetune whisper model using HuggingFace following this blog post Fine-Tune Whisper For Multilingual ASR with 🤗 Transformers and by adding Lora with approximatively 50h of annotated audio. While the finetuning works fine for the medium & large-v2 versions, when i try with the large-v3 the model starts to hallucinate after 400steps, and by hallucination I mean increasing WER with repeating words (i added prediction logs to see how the model reacts) (the training & eval loss are still decreasing).
