I recently encountered an issue where I was unable to use a system, despite trying various troubleshooting methods such as upgrading, shutting down and restarting, and reinstalling. It was frustrating and time-consuming, and I am hoping that by sharing my experience and the steps I took to resolve the issue, it may help others who may be experiencing similar problems. I am also searching for others who may have had the same problem and any solutions they may have found.
