@abdullahjhatial And does the same behaviour happen on a different computer? Please also try this suggestion from the thread I previously linked @Indighost said in Onion Tau not working anymore: Use ctrl+c to kill the program and try running it again Unplug the Tau Camera from the computer for 10 seconds, reconnect, and try running the program again Try switching to a high-quality cable! If possible, try using a not-super-long USB-C to USB-C cable from a reputable brand. Then try running the program again.
