Keyball44 - Right side of the keyboard where some keysare not working anymore

[KoichaDev]

Hello,

I have a Keyball44 and it usually works perfectly fine, but today for some odd reason, the right of the keyboard which is the first left column is not working anymore whenever I tried to press the keys. Does anyone know why this is happening?

I have attached image above to show example

Also the trackball has stopped working
