"Extension process Displays(2444) exited." when connecting via USB-C hub and HDMI

Hello Mac Community,

I'm facing an issue with connecting an extended display to my Mac. I attempted to set up the extended display using a USB-C hub and an HDMI cable. However, the extended display consistently shows "no signal," and my Mac displays an error message stating "Extension process Displays(2444) exited." I've tried troubleshooting on my own, but I haven't been able to resolve the issue. Any insights or suggestions on how to fix this problem would be greatly appreciated. Thank you in advance for your assistance!
