ChagtGpt app Only not connecting to Internet on Windows

Chatgpt was working fine till last night but suddenly this morning when I tried to use it on laptop running on Windows 11 it suddenly is not connecting to the net. It is working fine on browser and on my phone (also android). I tried uninstalling and reinstalling, flushed DNS, switched off firewall and defender settings, tried resetting the router, uninstalling antivirus, changing the time and everything but the problem still remains the same. I am also using claude on the same laptop and it also works fine . I am using free chatgpt and i use it on laptop and phone only. I have tried all the ways but the problem still persists. Any help would be great .
