Hello Natalie,
I am not completly familiar with the Bootcamp on a Macbook. But we have experienced similar problems on a normal Windows Laptop.
The problem occurs on laptops with more recent Intel HD/UHD Graphics.
At first please update your graphics card driver. If there are more than one graphics cards installed, then disable one of them and try to open the SSD through another one.
I don’t know if your MacBook Pro has a dedicated graphics card. If so you should prioritise it.
You could have a look at the following thread, where we have described in detail how to solve the problem:
