High school years bug

For some reason, every time I send two of my Sims to school and I follow them the timer will always go down to zero and stay on zero without morning time ever ending and class never starting. Not even my sims say “getting ready for class” anymore. I understand that sometimes when you send two sims at the same time can bug your game, but my game hasn’t been doing that at all until recently. I even sent one to school and it’s still got stuck on zero minutes. (a small example morning free time ends at 10:00 but since the timer is stuck on zero the UI will still say it’s morning free time even if it’s about past 10:00)                                                                                                                                              I don’t know if it’s just me. I’ve recently just got back onto the Sims and made sure i updated my mods and game.  I understand if there could be a ways to fix it but searched for every way I could and I couldn’t find anyone with this same problem. but I’ve tried everything. I’ve removed every single one of my mods and scripted mods which showed it was a the sims in general issue, I  repaired the game multiple times and I’ve deleted and re-downloaded it back. I DESPERATELY need help but I can barely find information about this type of problem
