Looks like a game bug, there's a use-after-free on a texture that can be observed even with wined3d:

I have already refunded this game. Even if I enter the game, it will crash halfway through loading the game. I am also a Steam Deck

[lzq960605]

You can try using 9.0 beta, and in desktop mode, you can enter the game with 9.0

I believe it would also be a good idea to upvote this thread with the bug report: https://community.lemansultimate.com/index.php?threads/proton-wine-dxvk-ctd-at-launch.1020/#post-5950

thanks!

Would be good if someone could post a complete log with wined3d enabled. IMO it will give some hints to the LMU devs where the affected texture is released/accessed related to the game's own log output.

Something like this command can be used: PROTON_LOG=1 PROTON_USE_WINED3D=1 WINEDEBUG=-all,+timestamp,+pid,+tid,+loaddll,+d3d11 %command%

("-all" turns off all unrelated log messages)

This should launch the game normally. Just reach the game menus and exit to prevent the log from growing too large. No need to force the crash on track loading, as it may not be related to this bug. (I would do this myself, but currently don't have the game.)

Did so, though I had to force exit the game since you still could hear music from the game being playedk even though the window did close. The log is still quite big, I compressed it to make the size manageable.

In my case, the screen goes black and returns to the desktop. I leave you the log in case it is useful:

Thanks @poljar and @leillo1975

I'll take a look and post in the LMU bug report thread.

This crash seems to have been fixed with build 14742905 released on the 20th of June 2024:

Build ID: 14742905 General

• Stability fixes to address crashes when loading into a race & loading a replay

The game still crashes if you attempt to start a race, but at least you can start the game now.

[leillo1975]

I have exactly the same problem, crashes on loading at 46% Tested with 9.0-2, Experimental and Proton-GE 8-25

I attached a compressed proton log file: steam-2399420.zip

[leillo1975]

LMU still does not work in the latest patch released today. Here is the proton log: steam-2399420.zip
