Qt for Python (PySide/Shiboken)

im on pyside6.8 and i have a strange problem. i used pyside s multithreading approach to update the state of a network connection then emit the signal on a loop to main ui. upon getting the signal ill send the value to qml file. the emitted value should change the state of a button. the problem is that most of the time it do, but sometime its not changing. everything in the ui is working fluently without any lags. i even have a clock with second counter that is working fine, even the button itself works flawlessly i mean the functionality is ok but the ui is not. the button has a title below the icon and an icon that these 2 should change upon receiving signals from python file. is the situation a known bug or im doing something wrong?
