I was having the same issue and not seeing the 5.2.0 option on my Epic Launcher.
What finally fixed it was just downloading and installing the launcher from the official site.

However now the issue is that although I can add 5.2.0 to my Engine Versions, the “Install” button doesn’t seem to do anything. Praying for a magic update to fix all this lol.
