jb_miraval  Has the save that generated this LE ever used mods, in particular a custom career?  If so, try adding back that career, or an updated version if necessary.

Please also let me know whether you can load a previously-unplayed household in the same save, or one of your other broken saves.  Use Load Game and select the household you want to test from there.

Thanks so much for replying.  Yes, all my saves are modded and I do use custom careers although as I can recall, the sims in that patricular household are in EA careers. 

My game and my EPs are currently re-installing as I was suggested to before your reply, I will do as you said regarding the careers and unplayed households when everything is done installing and let you know. Thanks again :)

I just added back all my custom careers and made sure they were updated however I still get stuck on the loading screen. I can also load into unplayed households just fine but not the family I'm playing with in any of the broken saves.

jb_miraval  Try moving the broken household to a different lot, either a default Maxis house or a blank lot, and see whether you can load them.  If not, split them into individual sim households and try again, the idea being that maybe you can isolate the issue to one sim.

Separately, if you're comfortable with various kinds of cheats, you could load a different household and try changing the careers of the sims in your broken household via cheats.  I'd have to look up what exact cheats to use and am not sure whether you'd need TwistedMexi's AllCheats, but if you don't know already, I can figure it out for you.

I know you believe they're all in EA careers, but the one LE you posted points to some issue with a career, so one of theirs could be broken anyway.  Or maybe you have multiple issues and adding back the custom careers fixed only one of them.

Feel free to post a new LE if you get one.

I seperated the household and it seems the issue is the teen in my household. She is homeschooled via the Education Overhaul mod by adeepindigo. Could that be the career issue? I tried adding the mod back (latest version) but it didn't fix the problem. I don't mind using cheats and can definitely download the mod you mentioned though I'm not sure which cheats to use.

Here is the latest LE I got. For some reason the file doesn't show up when I attach it:

I got the mod you suggested, thanks!

I followed the steps you said and was able to load her!  When adding my mods back, should I avoid re-enrolling her in the adeepindigo virtual school as that is what caused the issue?

jb_miraval  I am not completely convinced that the virtual school is a problem, and it's certainly not the only problem if the milestone fix helped since that's entirely unrelated.  (While lastexception files can be very informative, they're not 100% reliable.)  I would say that if you like the option of virtual school, you can re-enroll this sim, BUT immediately use "save as" to rename the save.  That way, you have a backup you can revert to if this mod breaks the save again.

Noted, thanks. Before adding back my mods I'm trying to figure out the issue with the two other saves that are broken. 

I did as you said for the previous save and I'm able to load in my 2 young adults, the child and toddler but not the teen once again.

Here is the LE I get:
