WoW Classic not launching

Cannot run wow classic at all. Tried all solutions, submited a ticket, tried gm’s solutions, nothing works. Had my pc formated and it ran when I freshly installed it the first day, then stopped again. Next day i tried with optional command -d3d11 and my firewall disabled and ran again for a few hours.

Now nothing works at all.

Retail runs normally by the way.
Any ideas? Blizz pointed me towards the community for answers

i have same exact thing, everything worked normaly yesterday but today wow clasic willnot run, wow retail works fine.

  1. i have found a way

nothing with reinstalls of wow or windows works (edited)

i need to disable interent then open wow clasic from folder not from batttle net, it works then it opens log in screen

then turn internet back on and log in

if i try normaly through battle net only wow retail opens up (edited)

if i try wow classic then nothing happens
