Hello,

On fresh Windows 10 with last updates, build 1909,

After installing Unity Hub and Editor 2019.2.21f1 and migrating my old project it's not opening. Free license.

Editor start and than returns back to Unity Hub.

Here is Editor log:

Exiting without the bug reporter. Application will terminate with return code 0

This bug only occur on projects that were created in Linux and then migrated to Windows. If you start new project in Windows it works fine.

And now, if I open project on Linux I have following error:

Curl error 51: Cert verify failed: UNITYTLS_X509VERIFY_FLAG_EXPIRED

I have tried to export package on Linux and import in new project on Windows. It works until I close Editor windows. After that - same problem.

“Ethernet Adapter is enabled even if you're not using it (you`re on Wifi)."- quote helped.

I don't know how long an access token / seesion id is valid, but you might want to remove this from your first post?
