Lost everything

I have clicked onto my gallery and every single build since 2025 that I have done is gone. Even the families I have made.. just gone. I cant even see the sims I JUST made on my library. Everything has been wiped since I updated and this is so ridiculous!!! I can’t just go back and recreate 50+ builds and families like wtf???? This is not even a single cc or “UI” problem.. what am I supposed to do now???
