Launcher 20.3.5: Install Engine and "+" do nothing, 0 entitled apps, EULA never shown

Summary

On my account, the Epic Games Launcher shows no engine versions in Unreal Engine > Library. The “Install Engine” button and the “+” button do nothing, and the Unreal Engine EULA is never displayed. The launcher log shows “EoshState = WaitingForBuildsAndItemFiles” and “found 0 entitled apps”. My GitHub account is linked. Already tried: reinstalling the launcher, clearing webcache, signing out/in, installing launcher 18.12.1 (it auto-updated back to 20.3.5).
