Windows capture showing unknown in obs studio

In OBS Studio i can record the whole screen but i am not able to capture any window (Window capture)
In window capute there is an option to select which window i want to capture but in my case it is showing
unknown.
But very few times it captures chrome and dolphin window but still it shows unknown at that option(where i select window)
In short i am not able to capute window through OBS studio

below i pasted log file of obs studio
