Hi, thanks for the report. 2GB file is way more for the investigation. Please simplify the file as much as you can.
Normally .blend files can be simplified by removing most objects and disabling settings, until the problem reveals itself more clearly.

Hi, I have simplified the model and found that it is the file packed inside the blend that has this problem, presumably it is this vdb file, do you have any suggestions from your side?

VDB files seems responsible. Deleting them doesn't cause the memory leak.

I seem to need this for my model, is there any other way if I don't delete it?

I also tried creating a new blend project and found that if I pack other vdb files inside blend there is also a memory leak, can this be fixed please? Thank you very much!

From where you got these vdb files?
