Editor Not Opening

When I open my editor, nothing comes up. I'm using 2019.4.12f1 LTS.
I've viewed the log and I think this is the issue:

Code (csharp):

1.  
2. [LicensingClient] ERROR Failed to connect to local IPC
3. [Licensing::Module] Failed to connect to channel: LicenseClient-ellio
4. [Licensing::Module] Successfully launched the LicensingClient
5. [LicensingClient] ERROR Error 0 while verifying Licensing Client signature (path: 12884, process Id: D:/2019.4.13f1/Editor/Data/Resources/Licensing/Client/Unity.Licensing.Client.exe)
6. [Licensing::Module] LicensingClient has failed validation
7. IPC channel to LicensingClient doesn't exist; falling back to Legacy licensing
8. [LicensingClient] ERROR Failed to disconnect local IPC connection
9. LICENSE SYSTEM [2020113 16:48:17] Next license update check is after 2020-10-12T03:33:23
10. LICENSE SYSTEM [2020113 16:48:17] Machine binding 4 mismatch: (value of current machine)  != [redacted]== (value in license file). Reason might be there is a hardware change on this machine after the license was activated.
11. LICENSE SYSTEM [2020113 16:48:17] Machine identification is invalid for current license.
12. Current license is invalid and cannot be activated. You must delete the license file and then activate a new license on current machine.
13. (Filename: C:\buildslave\unity\build\Platforms/Windows/Modules/LicensingLegacy/WinILicensingAdapter.cpp Line: 69)
14. Exiting without the bug reporter. Application will terminate with return code 0
15.  

I've removed and then reactivated the license twice.
Any help?

 

Have you tried this?

Yes.

 

Yes

 

i have the same problem, do you find a solution?

 

I fixed this and the "infinite import loop" error by moving the project folder from a NAS location to my local disk.
