Exact same issue except for me just trying to install a marketplace asset put me into this endless loop where i can no longer install any versions of the editor. I’ve done a full Rivo Uninstall, wiped local app data deleted all registry entries and still the issue persists. Wondering if they pushed something out by changing 5.6.0 from preview to full that has bricked it somehow.

Okay i just tried the epic launcher on a brand new windows 11 laptop and it has the same issue. Im convinced now there must be something in the last update that has bricked it

This morning it seems they have resolved the issue. At least for me both win 10 and win 11 machines can now install the engine, didnt have to uninstall the launcher or anything. Worth trying again this morning to see if its also resolved for you.
