802pdtpvtu5i Although the text is corrupted, this may be the "low disk space" error like the one on Blayer98's screenshot.
The error may also appear if OneDrive is involved; I believe OneDrive offers only 5GB of free storage. The Sims 2 and OneDrive are generally not a good combination since syncing user data with OneDrive may lead to neighborhood issues. At best, it could revert your saved files to a previous version or not let you save at all, at worst, it could corrupt the neighborhoods.
If you have OneDrive enabled, I strongly recommend disabling it (if you don't use it for anything else) or changing its settings to stop syncing The Sims 2 files. Puzzlezaddict has a great post on how to either disable OneDrive or prevent it from touching Sims files. Please check out the Managing OneDrive section in this thread:

Although these steps are written for The Sims 3, they will work for The Sims 2 as well; the only difference is that The Sims 2 user files are located in Documents\EA Games instead of Documents\Electronic Arts. Make sure to create a backup before making any changes, just like the post recommends.
