Your new camera requires ACR 14.2. If you follow precisely the directions found here, you will be able to update your ACR version to the latest 14.5.
The instructions are not entirely clear, but you should copy all files in the CC\File Formats\ directory to the Elements 19\File Formats\ directory.
I also recommend that before you copy and paste the files from CC to the Elements version 19 (Elements 2021) folder, rename the existing Camera Raw.8bi file to ~Camera Raw.8bi (original). Make sure to include the tilde (~) at the beginning of the name.
