Adobe Animate Symbols not saving properly

So, I use Adobe Animate 2023. I don't ever want to use 2024 since that version crashes constantly.
When it comes to symbols, I've come across a weird issue that only seems to happen in larger size files that I have. Sometimes, the file will take a while to save, which I assumed would be typical for the file size. However, randomly at times whenever I make edits within a symbol, save it, close the file, and then reopen it, those edits don't save. And when I say random, I mean it is completely random. Sometimes an added keyframe didn't save properly, sometimes changed objects in the symbol don't save, etc.
Anyone facing any similar issues? I can't post any files due to the type of issue this is.
