I’m unable to launch Steam version of the game. Last time I played Steam version was March 14th, and felt like playing again, but now I can’t. More info in this Discussion post I made.
I’m going to second the recommendation in that thread to check that your AV isn’t blocking either the game itself or the Denuvo component.
Also check the settings in Windows Defender Firewall, under the Advanced section - sometimes it seems it can automatically re-add the game even when supposedly disabled (maybe after a behind-the scenes definitions update?)
There is also a separate issue where the on-line component gets blocked when it tries to use the Terredo client, but I haven’t heard of that preventing the game itself from launching.
