I have just reinstalled Steam.
Redownloaded PoE2... it is now bouncing on my Dock and not launching.
Other games installed in Catalina had a "Verifying <gamename>" progress bar from the operative system.
PoE2 doesn't have it. Now the icon stopped bouncing but doesn't have the dot below the icon to show it is running. Nevertheless, if I go into the Force Quit menu PoE results as running (so it is not hanging). In Activity Monitor XProtectService is the highest energy consuming process.
The disk is working a lot so I suspect something is happening but the game is not launching at all. What can I do now?
