Hi NioZero,
If you haven’t tried 's solution yet (which currently is the best solution) could you post your Verbose logs from the launcher. Our devs are looking into and any help would be appreciated.
Just follow the 10 steps in the link below and post them here. Just make sure that they are the Verbose logs and not the standard logs. You can check by word searching them for the word ‘Verbose’ and they are generally larger in file size.
Afterwards, feel free to re-install and let us know if it works for you.
Cheers,
TJ
