Epic Launcher is broken... AGAIN!

We all know the issue of adding a line -OpenGL in the Epic Launcher properties. Now I have issues with an Update loop followed by an Unsupported Graphics Cards issue after the Update Verification. I’m using Win7, but my GPU is compatible. I’ve been using it without any issue for months and three seconds later, this problem happens out of the blue.

All my assets and Blueprint kits are in my vault.

I’ve tried everything (-OpenGL, reinstall, delete Web Cache, etc). Any new ideas of how to fix it?
