I found another fork bomb with partial-clone but not related to commitGraph
Here is the video: https://youtu.be/3Xun4PQNQC4

And here is the tree command, GIT_TREACE2 and GIT_TRACE_PACKET log https://drive.google.com/file/d/1mJ4-UcA8ytdjrYL7K6XxCtxys-DRRTqd/view?usp=sharing https://drive.google.com/file/d/1rOlskap5l2Z1N6LnaBgLhW-G_UF8zx3Z/view?usp=sharing https://drive.google.com/file/d/1zjI7Cm4aXv3fhPN3F_cwY15Ua-p4ncFl/view?usp=sharing

I still have the scene which can reproduce this bug. If there is something else I can provide, feel free to ask
