Null objects and solids randomly disappearing in After Effects 24.5.0

I'm experiencing an issue with Adobe After Effects (version 24.5.0) where my null objects and solids randomly disappear when I close or save my project. I've also noticed that this sometimes happens after I pre-compose layers, even if those layers are unrelated to the null objects/solids. The issue doesn't occur every time I perform these actions. For instance, I might pre-compose or save to test if the bug appears, and everything will seem fine, but a couple of hours later into the project, when I pre-compose again, my null objects disappear. Sometimes I don’t notice the issue immediately, making it impossible to undo, which makes this problem even more frustrating.

 

I appreciate any help you can provide.
