To add to Ofnuts, but in very direct way ➤ triple your RAM! Get 48 or 64 GB
I have 24Gb RAM, for an image half the size of yours, if I had 1 layer and use 1 or 2 filters, my computer hang for a while, and if I move a layer or try transform it, I have time to make a coffee, drink it, and cook something.
