Lightroom Classic crashes when importing pictures under Virtualbox Win 10

I have a Win 10 VM with 4MB, 4 CPUs, 128MB video. I have a local disk with several thousand pictures. I tried importing all and LrC just froze. I tried again with one folder of 178 pictures. It said it had imported all of them, but inly showed a random selection in the gallery. When I tried to load one of the pictures in the blank spaces it just sat with loading. I have run Photoshop on the VM (just about) is it really that reource heavy or are their some secret settings I am unaware of? BTW the pictures are all .jpgs
