I got an error everytime when I started with an example of project hmi-board-lvgl. RT-Thread Studio Version：2.2.6

The solution to the problem is to change the ARM Toolchains Paths But I cannot find a 10.2.1 version ARM Toolchains in my computer, is it a bug of RT-Thread Studio?

try download arm gcc 10.2.1 first
