Proton log file:
steam-2168680.log

Symptoms

• Game freezes after splash screen before the main menu

Reproduction

• Set compatibility to Proton Experimental or 8.0-4 or 7.0-6
• Install Nuclear Option (0.25.1)
• Start Nuclear Option
• Game will freeze after the splash screen

Further information

• The freezing issue does not occur with Proton 6.3-8, but the detection and handling of HID devices (in my case the Thrustmaster FCS Flight Pack with T.16000M, TWCS and rudders) produces completely unusable results.
• Player.log file from steamapps/compatdata/2168680/pfx/drive_c/users/steamuser/AppData/LocalLow/Shockfront/NuclearOption, in case it helps.
• Installing DXVK or xact via protontricks did not help.

[JT8D-17]

Further testing yielded:

• Nuclear Option works in the entire Proton 5.x and 6.x version bracket. Any older or newer, however, not.
• Sometimes, when switching from 5.x or 6.x to 7.0, NO works exactly once, although without detecting my HOTAS
• Trying NO on Fedora 39, latest packages, with Connamon and KDE Plasma in both X11 and Wayland, yields the exact same freeze error as on Arch, so the issue is not distro-specific.
• Output from running Steam from a terminal and attempting to start a completely reinstalled Nuclear Option with Proton 8.0-4 and a fresh prefix:

[JT8D-17]

The game works on Proton 8.0-4 if I unplug all of my controller devices (T.16000M + TWCS). If I plug in just a single of them, it will freeze after the splash screen.

Is this a Unity bug?

[JT8D-17]

The exact same isssue also occurs in "Reentry - an Orbital Simulator" (882140), which also uses Unity, so I assume that this is a general Unity game engine bug with Proton (or WINE) when any joystick is plugged in.

[JT8D-17]

The game now runs with the fix recently rolled into bleeding edge Proton (soon to be part of Experimental).
#7284 (comment)

[extract]

Game runs and seems to perform well, but I have input problems.
T.16000M + TWCS. I cant use the stick rotate (it's not being detected as moving in the calibration step) and if I bind the yaw axis to my rocker that doesnt work either.
