MO no longer launches skyrim. I woke up and in the morning it did. Now it won't. Any ideas why?

[Megaloblast]

Trying to have a day off and just finally play the game for once... I've changed nothing. It just doesn't launch skyrim anymore. It still launches tes5edit. 

[Megaloblast]

The launcher starts as well through MO, but when I hit play, no luck

why can't I delete or edit my posts?

[Megaloblast]

please delete topic, fault was my own

This has happened for me in the past as well. The reason was me having legendary mods loaded with old BSA format. You need to run bsa extractor: https://www.nexusmods.com/skyrimspecialedition/mods/974/?

 

I'm not saying this is what OP was having problems with, but that could be related.

So yesterday it was the same problem as Langmans, however, today, after having no issues all night. It won't start again. So I'm again at a loss. 

 

- okay, I think it was due to setting the overwrite path to the SSE data directory.

Error might be opening MO before logging into steam.

No. Shouldn't make any difference. Doesn't in my install.

Same happened to me out of nowhere after a couple sessions and turned out the skyrim process had stuck into the task manager and each time I'd click MO2 to run SSE it would load to 5M and just stack in the memory. Once I had them all manually finished the game worked perfectly.
