PC Problem About Dlc Db G6 Diesel Shunter & Rhb Anniversary Collection

Ahhhhhh......Today after I Install RhB Anniversary Collection & DB G6 Diesel Shunter, I can't open the game, I tried to verify the integrity of the game files, but to no avail, so I came here to post my problem.

My game can start to the loading interface, and then it will crash, I tried many times, but it still crashes.
And I have all the DLC of this game, and they are all enabled, but only when the DLC DB G6 Diesel Shunter or RhB Anniversary Collection is enabled, the crash will occur.

My operating environment:
Platform: Steam
Operating system: Windows 11 21H2

If anyone need more information, please reply me and I will add them.

I am not a native English speaker, if there is any problem with my English grammar, I hope you will understand, thanks.

--------Edit--------
The previous report seems to be wrong, It looks like the error is caused by RhB Anniversary Collection
I purchased two DLCs at the same time today, and this problem occurred after installation them, After many attempts, Seems only RhB Anniversary Collection will cause the collapse.

 

What are your Hardware specs?

I think these should not be a problem?

 

I tried these but it didn't work

 

Do you ahve any mods installed? Remove them first,they may cause trouble. Same for engine.ini changes.

 

No, I have never tried to install the mod, which is one of the reasons that make me feel weird about these crashes, I have never had a similar error before.
