Symptoms

Starting game immediately exits in failure within a few seconds, game window does not even get to open, steam client realises and stops showing the game as "Running"

Interestingly (an admittedly older version of) this game ran fine on my Arch Linux build, I can't remember, but may have been running the game without the runtime... But I have migrated to Ubuntu as the 20.04 release stability was appealing...

Reproduction

Installed game, start game

Possible lines of interest from the log:

Fatal Python error: init_sys_streams: can't initialize sys standard streams
Python runtime state: core initialized
OSError: [WinError 6] Invalid handle

As a possible note of interest, another game 1292020 (Armoured Commander II) was exiting with the same exception, until the change made by devs at Version 4.0.5. Their changes are described as: " Very minor update to fix the mouseover info on the Campaign Day view while in fullscreen mode.

Edit: Also changed the Pyinstaller settings to enable the console - this will create a black console window behind the game window, but it appears to have been causing issues for some players without it, and it should not detract in any way from the game. "

I wonder if there's an issue with Pyinstaller exes not being able to get back to a shell unless the app is started from a shell?

This issue seems to be resolved by Proton 5.0-8

Unity of Command 2 crashes often using Proton experimental and after upgrading to Kubuntu 22.04

Issue transferred from https://github.com/ValveSoftware/Proton/issues/5813. @mokmeister posted on 2022-05-02T12:48:00:

Unity of Command 2 was running well using Proton Experimental under Kubuntu 21.10. However, since upgrading to Kubuntu 22.04 the games crashes regularly. The latest crash produced these results in log.txt:

INF 2022-05-02 13:29:38,437 tools.steam_api:230 Shutting down Steam ERR 2022-05-02 13:29:38,442 uoc2-exe:24 Traceback (most recent call last): ERR 2022-05-02 13:29:38,442 uoc2-exe:24 File "uoc2-exe.py", line 17, in ERR 2022-05-02 13:29:38,443 uoc2-exe:24 File "E:\code\uoc2\uoc2\main.py", line 311, in main ERR 2022-05-02 13:29:38,444 uoc2-exe:24 File "E:\code\uoc2\engine\ui\system.py", line 716, in main_loop ERR 2022-05-02 13:29:38,444 uoc2-exe:24 OSError: exception: access violation writing 0x0000000000000054

based on the crash log, developer reports that the game crashes in SDL_GL_SwapWindow()

Hello @mokmeister, please add PROTON_LOG=1 %command% to the game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.) Also, please copy your system information from Steam (Steam -> Help -> System Information) and put it in a gist, then include a link to the gist in this issue report.

This has regressed in between 7.0-6 and 8.0-2.

Repro steps:

• Start a campaign (this also fails on saves created under 7.0-6, to be clear, but doesn't fail on an identical setup with 7.0-6)
• In the campaign, enter a scenario
• It fails to launch, there is a small popup window with the title "cx_Freeze: Pyth... in main script" giving no error message, directing you to look at a log file in %localappdata%/.uoc2/log.txt. This contains the following log: INF 2023-06-04 15:31:34,240 tools.steam_api:267 Shutting down Steam ERR 2023-06-04 15:31:34,244 uoc2-exe:24 Traceback (most recent call last): ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "uoc2-exe.py", line 17, in ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\uoc2\main.py", line 311, in main ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\system.py", line 690, in main_loop ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\system.py", line 1046, in _run_coroutines_and_signals ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\tools\coroutine.py", line 107, in cr_switch ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\tools\coroutine.py", line 137, in switch ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\uoc2\main_screen\ctrl.py", line 1839, in _cr_setup_world ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\state.py", line 110, in _switch_state ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\state.py", line 121, in _switcher_gen ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\state.py", line 186, in dispatch_internal_event ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Env\Py311\Lib\site-packages\pydispatch\robustapply.py", line 55, in robustApply ERR 2023-06-04 15:31:34,244 uoc2-exe:24 File "C:\Code\uoc2\uoc2\main_screen\ctrl.py", line 384, in on_leave__campaign ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\ctrl.py", line 30, in deactivate ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\state.py", line 110, in _switch_state ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\state.py", line 121, in _switcher_gen ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Code\uoc2\engine\ui\state.py", line 186, in dispatch_internal_event ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Env\Py311\Lib\site-packages\pydispatch\robustapply.py", line 55, in robustApply ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Code\uoc2\uoc2\main_screen\campaign_ctrl.py", line 158, in on_leave__active ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Code\uoc2\uoc2\state\campaign\campaign.py", line 252, in save ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Code\uoc2\tools\file_utils.py", line 88, in copy_tree ERR 2023-06-04 15:31:34,245 uoc2-exe:24 File "C:\Programs\Python311\Lib\shutil.py", line 559, in copytree ERR 2023-06-04 15:31:34,245 uoc2-exe:24 OSError: [WinError 123] Invalid name: 'C:\users\steamuser\AppData\Local\.uoc2\save\campaigns\don.usg'

I can confirm that starting a campaign still crashes as of Proton 9. Proton 7 works fine with campaigns with PYOPENGL_PLATFORM=nt %command% in Steam launch parametre.
