macbook professional – Keyboard mixture not being registered in any respect

My machine is a 13 inch Macbook Professional, M1 2020 operating on Monteray

I’ve an issue with this particular keyboard mixture: management + choice + up, which isn’t registering in any respect. I discovered the issue as a result of that keyboard mixture is utilized in Rectangle.

After I tried the mix in a keyboard tester web site, (e.g. this one), or tried to set a keyboard shortcut underneath Keyboard > Shortcuts desire, it doesn’t work.

The odd factor is that solely this particular mixture will not be registering. Different related combos works positive:

• management + choice + left
• management + choice + down
• management + choice + proper

I’ve tried:

• Unplugging every little thing and attempting the mix on the mac keyboard
• Shutting the machine down and beginning it once more after ready for not less than a minute
• Killing many of the background apps
