After patch 4, game crashes at 22% loaded when using Proton GE 8.9

FYI:

After updating to patch 4 today, the game crashes when it starts up. It does not make it to the main menu, crashing at 22%.

Here's the error message: https://imgur.com/a/DlWGA4Y
Wine C++ Runtime Library

Playing on linux with Proton GE 8.9

I found a workaround, which is that the bug goes away with Proton 8.0-4.

Same here with ProtonGE 8.11 and ProtonGE 8.22

There's more Linux users encountering the same problem

I tried using Proton 8.04 also, which actually shows the launcher (where this is not the case for me when using the GE versions). But using DirectX 11 just results in high CPU usage and a black screen with only the hand cursor, and when using Vulkan I eventually get the same error as shown in the screenshot

Ah dang, I should have tried playing a bit more before considering the issue solved. Thanks for the head's up!

Like you I got the Larian launcher with Proton 8.0-4 and I hadn't had it on GE 8.9 or 8.3.

[Metalfyre]

It's funny that in my error message it states that it might be an issue not related to Larian and the game. But it occured first after the patch and I see a lot more people having the same issues. So yes Larian, it's definitely an error on your side! ;-)

Following up - I was just able to play a couple hours without issue using Proton 8.0-4 and DirectX.

My computer has an AMD Ryzen 7 1700 x 16 processor and AMD Radion RX570 gpu. Performance seemed a tad slower than on Proton GE 8.9 but still pretty functional on my end.

+1, another here with the "Assertion failed!" error, "!status && vkCreateComputePipelines". Proton-GE

Same error here, steam deck proton GE 8.11 and 8.22! started right after the patch 4 update, it was working fine before... launches ok on proton 8.0-4, but fps is waaay down :(

I get nothing on 8.0-4. Just crashes

[Metalfyre]

Using DX11 solves the graphical issues I was having, but I prefer Vulkan and that still has graphical issues at times.
I upgraded my Nvidia drivers to version 545 where I don t get the crash anymore at the start screen. Using Proton Experimental (or ProtonGE 8.23) with DX11 enabled it seems to work fine. It s just that startiing up the game, I have to Alt-Tab out to my (open in the background) file explorer (and it has to be maximized) for the game to continue to load. I have to repeat this alt-tabbing until I m actually in the game, and then it runs smooth. Bear in mind, when alt-tabbing out of the game to your file explorer may take up 15-30 seconds, and everything seems to be frozen, but it isn t in reality) The file explorer is not visible, until I maximize it from my taskbar (that can also take 10-15 seconds before it does), once the file explorer is visible (and the game is visible behind it), it starts loading the game further.
In the Launch Options for this game (in Steam) under the properties for this game I use this line:

eval $( echo "%command%" | sed "s/Launcher\/LariLauncher.exe'.*/bin\/bg3_dx11.exe'/" )

So, either use latest version of Proton Experimental or ProtonGE (8.11 or higher, 8.23 is latest) and start the game in DX11 mode with that launch option. And it should work.
This is on Linux Mint 20.3

Same. Just updated my wife's steam deck and when we went to play we're getting the "Assertion failed!" message and crashing. I was hoping this would solve it, but 8.4-0 and/or launching in DX11 aren't helping. Still just crashes.

I'm pretty tech-dumb, so I guess I'll be waiting for another patch and hoping it fixes whatever this one broke.

Had the same problem. Verifying game data solved my problem

Hmm, it didn t for me. I mean DX11 still works great, but with Vulkan, nope, same issue as before verifying game data. I even reinstalled the game at one point. Didn t solve it either

This indeed fixed the Vulkan isssue for me. Game works with Vulkan as it did before patch 4. Thank you so much for providing this link for the fix :)

no longer launches on Mac

[Potato Puns]

Same error here! r7 3700x & RX 6800XT. Proton-GE 8-25 with launch options skip launcher and dx11. None of these have worked for me.
