@Brii0423 What I took from the first blog post I linked, was that sims that are reset (like you described, stop what they are doing, and very suddenly); is a old problem in the game, and that EA are aware and working on it. The blog is continually updated, so while the post may be old, I still see the info as valid.
Creating a new folder with nothing in it will exclude your mods as an explanation to the issue.
I could not access your pictures you attached before, and now that I can, I have a problem seeing what they say, they are too small. But it looks like they are a message from TwistedMexi's mod Better Exceptions, so you might want to ask at their page about them. You can also upload the LastExceptions.text files here. You find them in the Sims 4 folder. Just copy/paste under a spoiler. I do not promise I can understand them, but I will try. 🙂
