This information is useful, it could indicate several things:
Outdated drivers: It is possible that when you download from Windows 11 to Windows 10, your drivers have been misconfigured, implying that you will be downgraded to a previous version that you had before updating to Windows 11. I recommend checking if all the drivers are updated, especially the GPU and CPU
Problems with integrated graphics: Some Intel processors have integrated graphics, sometimes it can cause problems (it happened to me with RDR2), you try to open the game and it detects the integrated graphics, since it cannot work with it, it tends to close. I don't know if this is your case, but if you have an Intel with integrated graphics, try deactivating the processor's graphics with the device manager, disabling it.
Windows update pending: Sometimes when Windows has a pending update, the games start to go wrong, I don't think this is the case, but check if there is a pending Windows update, if there is, update it, if not, then we discard this.
To be honest, I can't think of much else, maybe it could also be a gameconfig file thing, since the default gameconfig file doesn't support large amounts of mod vehicles, very high quality textures and that kind of thing, try downloading a file of modified gameconfig, maybe that will help you if that is the problem.
As a last recommendation, if none of this works, you could reinstall the game from 0, doing a clean installation, deleting all the files, mods and so on, if you leave it completely vanilla, it should work perfectly and then you can reinstall the things you had little by little to see if it was one of them.
Good luck fixing it, let me know if you have any progress, and if I can think of any other possible solution, I'll let you know.
