Everytime I tried to use the Patch with scenario 10/16 of the new locomotive, it either crashes the game at the begining or somewhere between the 2 tunnels, and the same error also happens when trying to use the livery editor and the error is the following: LoginId:879ddfba4fe0a921da895ba85c03d1f8 EpicAccountId: Assertion failed: [File:Unknown] [Line: 263] CommandList->Close() failed at F:/Dev/TSW2_SUBPC/Engine/Source/Runtime/D3D12RHI/Private/D3D12CommandList.cpp:126 with error E_INVALIDARG TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping TS2Prototype_Win64_Shipping kernel32 ntdll I have already done hundreds of file integrity check, and no errors, I have downgraded the video driver from the latest that just came out from Nvidia a few days ago (2020/12/24), to a previous version that is actually 2 version behind
I get exactly the same error when I try to select the 1972 Stock in the menu to play a service on the Bakerloo Line. I have done a file integrity check as well but the problem is still there.
By any chance, is either one of you running the game in DX12? If you are, it will crash like this every time you open the livery editor OR select a repaint in the service menu (as DX12 is not supported).
I just tried it myself with DX12 active and just like you said, I crashed when getting into the editor. So that is at least one thing that makes it crash for sure. Not giving up DX12 though, no way.
So far the same for me, when I remove the -DX12, I can access the editor, and I am now trying to complete the journey for the C40 or something locomotive to see if it will fix the issue as well
And as an update, I was able to finish the journey 10/16 of the C-40 locomotive successfully by removing the -DX12 switch Thank you for the help and tip
