I'm seeing this exact Cinnamon problem on the Pinebook Pro (Rockchip rk3399).
I get the same error message flagging Util.latinise. I see no Start menu button. If I press the hardware start button on my keyboard I see a blank menu box appear with no icons or functionality. Under Armbian/bookworm, which I currently run on the Pinebook Pro, there is no problem; Cinnamon seems to work fine under Armbian/bookworm.
The problem appears only with Armbian/trixie.
