SH3 + GWX under steam proton crashing after first patrol loading bar fills up

[promitheas]

[SOLUTION AT END OF POST]

Hello guys!

A few days ago I wanted to get back into SH3, so I installed it through steam and got LSH3 set up with Ahnenerbe WideGui 1920 x 1080 Final mod, and it worked pretty good!

However I quickly realised that I want a little more control over what mods I am running, and so decided today to clean install the game and install GWX. I got everything setup (including the 4gb patch which I had to run through wine). After running the patch through wine I got the message that the exe file was patched successfully, however when I run the game using SteamTinkerLaunch as the compatibility layer (it in fact uses proton 9.0), it crashes to desktop. Specifically it crashes a little after the loading bar for my first career's first patrol fills up.

Here is a list of the mods I have enabled as a screenshot:

And here is a screenshot of where it crashes:

My system specs are:
CPU: AMD Ryzen 7 5800X3D
GPU: AMD Radeon RX 6700
RAM: 128 GB
OS: Arch Linux kernel 6.10.7-arch1-1

If anyone has any insight on what the issue might be, or where I can look for more information (logs etc) please let me know! I will happily provide any extra info anyone asks for.

Many thanks in advance!

P.s. Sorry about the imgur links if thats considered bad practice, I couldnt figure out how to embed them in the post directly.

Edit 1: Training missions work - load quickly
Single missions work - load fairly slowly (~2 mins from when the loading bar fills up to when I get in the mission)
Its just careers that dont. I tried this with 1st and 2nd flotillas

Edit 2 (SOLUTION):
So what ended up working for me was simply making the game run using proton 6.3-8. I did try version 4.3 as well, but that didnt seem to be working that well with the widegui mod I have.

Edit 3: Editing to add 2 more things to the solution. Because of frequent crashes while in the career patrol, I ended up lowering the Particle Density to 90 and also do not create any saves while out on patrol. Not sure which of the two actually stopped the crashing, but so far I've played for about 20 hours with no crash.
