"After Effects warning: could not rename the file" issue

Hi!

I've reinstalled after effects after having to reinstall windows 11, and now, every time I open a file, send a comp to the render queue or try to save the project, a warning pops up: "After Effects warning: could not rename the file" (screenshot below). Before having to do this, everything was working just fine.

I already tried to run it as administrator, change permissions on both, after effects folder and preferences folder, and even completely uninstalled all adobe apps, including the creative cloud app, removing every trace they left, and reinstall everything again. I still get this warning.

Can someone help me please? It's a little annoying to get this warning pop-up all the time.
