Ideas
I'm currently playing a household that contains a teen and a child, When I went to check how long I have until my teen ages up I noticed the panel was glitching and I couldn't scroll down in the panel, then when I went to save my game I could not open the option menu to do so. I then force quit the game and went back in and traveled to a lot, and when I opened the simology panel again it bugged my game and I was not able to travel back to the house lot or open the option menu. This bug ruins the game because even though I know what is breaking my game I forget and end up opening the panel again by habit, so I really hope they are able to fix it soon because it is unplayable and I was looking forward to playing the new expansion pack. I have not been able to test if this happens on adult sims, so if you know please comment because I unfortunately might have to age up my sim early, thank you. (I HAVE NO MODS btw) good luck simmers ♥
I'm currently having the same issue, however I DO have mods. I spent sometime taking each mod out to be sure it wasnt the mods messing with the game. I even have a test game save where I test out issue with my mod and game. So far my test save is amazing I can open simology and even edit my sims in cas without the loading screen being forever and game crashing. But my current save with tons of progress will "crash" i.e. me not being able to save game or press any other options like opening sims inventory. Just to go around and find teen simology and cas is the ONLY one messed up. Infants, toddlers, YA, Adults and Elders are all fine, as long as you don't open up simology on your teen sims the game wont break, I haven't tested if it'll still break for teens who age up to YA.
Edit: Just aged up my sim, it DOESN'T fix the problem. EA needs to fix this issue and fast.
