Can't save file and InDesign keeps crashing

I have the latest version of InDesign, I uninstalled it, installed it, went back to the older version, it doesn't matter, it keeps doing it - I can't save the file, it keeps reporting an error, it crashes, after opening it I can't save it again, I can't work. I'm completely exhausted from it. I've seen a lot of people complaining about it here and for 2 months now, why aren't you doing something about it? It says it has something to do with Windows, I'm not an IT specialist, I don't know what to do at all. I just want it to work for me and I can work. Creative Cloud costs a lot of money and you don't do anything for us. I have the same thing installed at work and it doesn't work for me there at all. Only on my computer at home. I want to know what to do.
