The latest discovery is that when I first connect to the computer using Xiaomi Pad 5 Pro, the keyboard input is invalid. No matter how hard I press the keys, the remotely controlled computer cannot type words.
Then, for testing purposes, I tried all the keys on the keyboard and found that when I pressed the Tab key, The element in the Rustdesk taskbar of Xiaomi Pad5 Pro has been selected, and pressing the Enter key will trigger a click event in the title bar like a mouse click operation. Then I created a new txt text file on my computer and tried to input some text. Surprisingly, the buttons worked!
So I tested it several times, from initially connecting to the keyboard and typing was invalid, to pressing Tab, then Enter, and then entering text in the txt file, and the keyboard was working!

I hope the above feedback can help you locate the problem!
