Dark mode preference resets

The following only happens on the Mac Version of  Adobe Premiere Elements 2026 only:  I set preference to dark mode, but upon reopening the app it is always back in light mode.

Windows versions of Premiere Elements 2026 & Photoshop Elements 2026 as well as the Mac version of Photoshop Elements 2026  do not exhibit this behavior.

Running Tahoe 26.5.1

Appreciate any help. Thanks
