I was doing my project. On the next day after rebooting my pc, Unity gave an error.
“Failed to start the Unity Package Manager local server process. Make sure the process [D:/Unity/2019.4.11f1/Editor/Data/Resources/PackageManager/Server/UnityPackageManager.exe] is not blocked by Windows Defender or any other anti-virus configuration.”
At first, i was using Unity 2020.1.8f1. When this error happened, I updated Unity Hub, and all was perfectly working until next reboot. I’ve tried to reinstall Unity, downgrading and updating it, but it doesn’t working. Also, when i checked the location of Package Manager server, when i launching Unity, it just disappears. I’ve tried to copy it back, but it disappears anyway. By the way, i don’t have any anti-virus, my Windows Defender is disabled and my firewall also disabled.
Versions: Unity Hub 2.4.1
Any version of Unity.
