Steam Log

steam-544750.log

Symptoms

The game main menu is empty, with no logo, but fully operational, I believe the game has a video playing after entering for the first time, but it simply doesn't play, trying to manually trigger any cutscenes in the galery mode also doesn't work.
Also, the game says there is no Network data available, so I can't get online.
There is one more problem, this window appears after exiting the game:

Reproduction

Any video/main menu trigger. And trying to get online on the menu/loading the game.

Updates

1. After some testing I found that even on Windows, after having played the game on Linux, I can't connect to the servers. Some other people seem to be having the same problem from what I've seen on the Steam Forums. Even with a new save data and on Windows, I think playing on Linux right now somewhat flags the account, or something like that preventing from going online.

2. I emailed Bandai and got a response that their team was aware of the online issues, and that it was redirected to and internal team to see if it could be fixed.

3. It seems that right now I can finally go to online on Windows, as I don't wanna risk not being able to go online again if I play on Linux, I'm gonna wait and see if someone tests and see if they can play online on a Linux Distro and also if the cutscenes issue is still present or not.

Start with the linked steam-544750.log and the full system information Gist, then reproduce the empty menu, missing cutscenes, and post-exit window using Proton 3.16-3. The report also mentions online connectivity, but later updates indicate that issue may be external to Proton; completion criteria are not defined.
