Problem of the keyboard shift key in game

My problem is when I am in the game, the shift + right click not working.
When I start the league, it seems normal and I can use the shift + right-click function. but a few minutes ago, I could not use the shift + right-click function at all.
I tried to reset and change the key position, like changing the tab to shift, and it worked and showed the minimap. So that means the shift key function is working, but still cannot use the shift + right click like click the item to sell or fast allocate skill points etc... After that, I even restart my computer and reinstall the whole game, but the problem still happens.

Yes, the Ctrl + left click is working, but in the past, I'm using shift + right click. So that means GGG changed the key combination, and now how can I divide the item like 3 Chaos Orb to 2 Chaos and 1 Chaos? Since the game function description still hasn't changed.

The problem is solved. The key combination changes. I need to get used to it again.

Maybe I'm used to the Last Epoch key combination. Thank you so much.
