Shift+arrow keys deselects instead of adding next image to selection

Issue: Shift+arrow keys deselects instead of adding next or previous image to selection in grid view.

• Lightroom Classic Version Number: 11.4.1 
• OS Version Number: MacOS 12.4
• 2021 mbp 16", Eizo monitor, Wacom pen connected.
• Same issue happens on 2015 mbp 15" on Catalina.

Steps to reproduce:

1. Browse images in grid view.
2. Hold shift and press left or right arrow key, to select multiple images.

Expected result: Adding next or previous image to selection, happens most of the time.
Actual result: Deselects all images. Happens ≈ 1/3 of times with shift+left arrow key, and 1/10 of times with right arrow key. Same result with both left and right shift keys. Same result  happens with shift + up or down arrow key as well.

The undo - redo queue doesnt register anything. If I browse using the arrow keys from image 1 and to the right (2, 3, 4...) and I want to add the next image to the selection with shift+arrow key, it deselects everything and show "Undo go to next photo" as next undo step. When pressing undo it selects the previously selected image (If image 4 is highlighted, and I want to add image 5, when pressing undo it selects previously highlight image, image 3). If the previous undo step was changing from Develop to Grid view or something similar, this becomes a very frustrating process of un-doing and re-doing to keep the workflow at a high speed.

Can you provide more details about your hardware? Is this a laptop or desktop with extended, separate keyboard? If a separate keyboard is it wifi, battery operated, hardwired? It will be helpful to eliminate the keyboard as a culprit. When testing to recreate on my laptop the shift + arrow works as expected.

I have the same issue. In the library module, the glitch can be replicated by pressing the right arrow, left arrow, then shift + right arrow. Then it will correct itself, but the reverse (left arrow, right arrow, then shift + left arrow) will do the same glitch. It will no longer select images and instead jump to the very end (or beginning) of the library.
