I have the same issue, regardless which type of guest I create...cannot un-check 3D acceleration without crashing Workstation Pro 15.1.0. Host is Win10 1809.
If you create a new VM with "create new VM wizard" do NOT use the "customize hardware" button -
instead close the wizard and then open the VM and modify what ever you need to via the menu: "VM > Settings "
Unfortunately thats a bit tricky if you use "easy install"
