I have tried multiple times over the past 3 days to buy gems in the Arena online store. Each time, when the purchase button is clicked (so it would normally pull up the external dialogue box to enter payment information), instead the screen grays out and it is stuck on "Waiting for the Server..." with a spinning circle indicator and the app freezes and can't do anything until I quit it. This is happening on the desktop application for MacOS Sequoia 15.6.1.

This problem has been posted by others already, I think, but I'm submitting this as a top-level post to show a list of attempted fixed that have not worked:

Restarting Arena

Restarting my computer

Logging out of Arena and logging back in

Uninstalling and reinstalling Arena

Uninstalling + reinstalling the Epic Games Launcher, including manually deleting all local log files for the Epic Games Launcher that I could find (~/Library/Application Support/Epic + ~/Library/Application Support/EpicGamesLauncher + ~/Library/Caches/com.epicgames.EpicGamesLauncher + ~/Library/Logs/EpicGamesLauncher + ~/Library/Preferences/com.epicgames.EpicGamesLauncher.plist + ~/Library/Saved Application State/com.epicgames.EpicGamesLauncher.savedState + /Library/Application Support/Epic + /Library/LaunchAgents/com.epicgames.* + /Library/LaunchDaemons/com.epicgames.*)
