Good afternoon,
I’ve downloaded the new version of Unit 2019.3.7f1 but have been unable to open my project in the new version. I keep getting a ‘Unity Package Manager Error’ code. Please see the requested attached files. Any help in resolving this issue will be greatly appreciated.
From the provided screenshots, it appears possible that this user could have firewall issues. I would recommend you try the configuration suggested in the sticky post referenced above.
