Photoshop intermittently behaves as if the Shift key is being held down

For nearly five years, I have occasionally experienced an issue where Photoshop suddenly behaves as though the Shift key is being held down, even when I am not pressing it.

For example, when I use a transform shortcut, Photoshop repeats the transformation as if Shift were pressed. When I merge layers, it sometimes merges all layers as though I were holding Shift. This happens despite the Shift key not being physically pressed.

Pressing the right Shift key once temporarily restores normal behavior, but the issue eventually returns. I have been dealing with this problem for about five years.

I have also found several older posts describing the same issue. Is the Photoshop team aware of this bug? Is there any permanent solution or workaround?
