I confirm:

• that I haven't found an existing compatibility report for this game.
• that I have checked whether there are updates for my system available.

Symptoms:

The game hangs after clicking the launch button and no window shows up. It works with Proton 3.16 and 4.2. I've already figured it out what's happening on Proton 4.11 and 5.0. A process called WLIDSvcM.exe prevents the game from launching. If this process is killed, the game works.

I know Lutris has a "exclude processes" configuration that allows to workaround this sort of issue. Would it be possible to add an environment variable to fix this ? Or is there a way to blacklist this process ?

P.S 1: I haven't put the logs because none is produced due to this process hang.

P.S 2: This game already has an issue related do Xbox Live even when running on Windows. But it works if you install the Steam community patch on the installation dir (/home/$USER/.steam/steam/steamapps/common/Street Fighter X Tekken).

Reproduction

1. Install the game
2. Try to launch it ( it will hang )
3. Kill the opened processes through the command line or other tool (the "Stop" button doesn't work)
4. Install the community patch to /home/$USER/.steam/steam/steamapps/common/Street Fighter X Tekken
5. Launch it again ( it will still hang)
6. Find out the id of the process called "WLIDSvcM.exe" and kill it.
7. The game will launch

Start by reproducing the launch hang with Proton 5.0-5 and confirm that WLIDSvcM.exe is the blocking process, then compare behavior with Proton 3.16 and 4.2. Done means Street Fighter X Tekken launches without manually finding and killing that process, including when the community patch is installed.
