Have been battling this very same thing in the last couple days. In the research I have done it looks like it is a bug and the “solve” is to open the command palet and change button to button reassignment to active pallete. It actually does work but the is just a workaround for a crazy problem. I even mapped the selection tool to my keyboard and it didn’t even fix it, the toggle never worked if I was stuck in hand mode.
