Sony a6400 --Elements 2019 can't open pictures

Okay, so I have used my old camera -a Sony a6000 3 weeks ago, and was able to transfer images over. ---I shoot everything in RAW format.

Last week, I bought the new Sony a6400 and took 81 pictures a few hours ago.

Upon transferring the a6400 photos to "Adobe Photoshop Elements 2019" it says that the images aren't supported and that I need to update it.
--If it makes any difference, I have a 2015 Macbook Pro 15" running the macOS Mojave 10.14.5

So, I went and found the "Adobe Camera Raw and DNG Converter," and downloaded the LATEST one.

Also, in the "Adobe Creative Cloud" it says I have the most updated version of the DNG Converter.

Let me go over the key details again:
I have a Sony a6400, the lens I am using is the "Sony E 18-135mm F3.5-5.6 OSS" ---which is listed as a supported lenses

I have Adobe Photoshop Elements 2019
I have updated the Adobe Camera Raw converter to the latest.

What else am I supposed to be doing, to be able to use photoshop elements to view my RAW files?

UPDATE:
I downloaded a trial of Adobe Photoshop CC 2019 ---I was able to open the RAW images on that program, but not in the Photoshop Elements
