steam-1301350.log

Note that the log was generated using WINEDEBUG=-seh as the game continually throws exceptions and the stack trace is printed for them, ballooning the size of the log to 20MB+.

Symptoms

The game initially loads but does not allow the user past the logo screens saying that it cannot connect to Steam. The game logs (located in the game data directory) show (ignoring all the exception stack traces):

10-13 08:26:35:469 [Error] [3] [1] [Steamworks.NET] SteamAPI_Init() failed. Refer to Valve's documentation or the comment above this line for more information.
10-13 08:26:35:471 [Error] [3] [1] SteamScript.Check: not initialized!
10-13 08:26:35:473 [Log] [3] [1] Steam should be open before starting game

Full log attached, and log without the stack traces.

Reproduction

Start the game.

Start by reproducing Party Animals Demo with Proton 5.0-9 and review the attached steam-1301350.log, full game log, and trimmed.log around SteamAPI_Init() failure. Done would mean the game passes its logo screens and initializes its Steam connection; the report does not identify a source file or test to change.
