[Help] Skyrim studently crash on startup without any change in mod list

[assassin394]

Hi. My game was working fine yesterday but now, everytime I try to launch it just crash on startup before even get to bethesda logo. I check MO2 plugins panel, LOOT and there is no missing master. No crashlog since the game crash before it even start. I checked skse64.log and all .dll plugins is up to date, no error. I disable all mod and the game run fine so it must have something to do with my mods list. But I don't understard why it work fine before and suddently not. Is there a way to identify the cause without have to check every mod one by one?

Mod auto update?

The game probably did start, or rather, the game process most likely did get resumed by SKSE. If it didn't, then the issue could for example be in an SKSE plugin that crashed before Crash Logger SSE managed to set up its exception handler. Something like this might show up in skse64.log simply as some dll missing from the list of successfully loaded plugins - i.e. the log being cut short. You'd perhaps need an skse64.log from a working session to spot the differences more easily.

 

More likely reasons for why there is no crash log:

1. Game terminated normally for some reason.
2. An SKSE plugin terminated the game for some reason.
3. A 3rd party terminated the game for some reason.
4. You have another module or process that registered an unhandled exception handler in Skyrim or a debugger attached to Skyrim which hijacked the unhandled exception before Crash Logger SSE.

Regardless, seems like the solution is going to be quite simple:

Time to trial-n-error it.

If you actually want to find out what's going on then you'll probably need a debugger. Start by seeing if it can catch an exception. If the game just terminates with no warning, then this is going to require more work.

Thank you for taking the time to answer. The game just crashes with no error. When I run skse from MO2. Skyrim.exe process will appear for like 10-15 second then disappeared and the game never launch. I have Crash Logger SSE AE VR - PDB support installed but there is no crashlog.

 

 What do you mean by debugger?

skse64.log

Do you happen to have any mods that replace the various game startup menus? 

 

Attractive Start Menu for example

I would be suspicious of mods with dlls in them.

Nevermind. I figured it out. I actually do make a little change in mod list. I update a voice pack patch for DBVO mod called Valerie DBVO - Even More Patches. It only contains voices files. No esp, no dll so it never crosses my mind that it's the cause for crash. I removed it and now the game worked fine.

I guess the game got far enough to start loading voice files. Quite interesting that it's even considering those at the start of the game. I would have guessed it would cache them when dialogue starts or something along these lines. Maybe it caches all voices that are used for greetings and ambient NPC background dialogue.

 

Anyhow, wouldn't have been my first pick. 👍
