“Fail to start the unity package manager local server process. Make sure the process [C:\Program Files\Unity\Editor\Data\Resources\Package Manager\Server\Unity Package Manager ] is not blocked by your anti-virus configuration”
I get this error when i try to open unity editor either via unity had or directly unity editor.
My version of unity is 2019.2.18f1 but before this version, unity 2019.2.17f1 also get this error. The error hasn’t existed in unity 5.4.0f2.
My OS version is window 8.1 pro 64bit.
2 things come to mind, anti-virus is blocking untiy, or firewall settings is blocking unity.
