Decided to try DEI after many years but found Steam's launcher crashes either on startup or starting/loading a campaign. I tried to swap to Mod Manager and it doesn't even load the mod packs, despite all of them being present in the data folder, acknowledged as such by MM, the data path being set correctly, and profiles of various combinations of the mods being savable and loadable on MM. Despite all that MM just loads into an instance of vanilla every time I hit Launch, and I've tried running just the 2 base packs for DEI, as well as several combinations of submods. I also tried running MM as admin, checked around on forums and made sure to I don't have any launch options present, cleaned out the scripts folder, unsubbed all my Steam mods, etc. None of the fixes I've found that work for others has worked.

If I recall correctly I ran DEI fine years ago just installing the mod files into /data/ and running them off MM. Am I missing something?
