Issues with importing PPT and PPTX in captivate 2019

After updating to 2019, I am unable to import already created and saved PPT and PPTX into captivate. I am able to create one with two or three slides and it will work fine. It will get to slide 30, freeze and give an error that I need to install a JDK file. For reference, I am on a Mac, all products are updated.
