After Effects stops working on specific projects

Hello,

After Effects stops working on certain files, as you can see in the attached video. There is no progress in the preview section, even though I move forward in the timeline. Additionally, the save screen that appears when I close the file stays on top of all windows, and it doesn’t go to the background even when I open other applications or finders.

To troubleshoot, I unchecked the "Enable Hardware Accelerated Decoding" option in the Import section, but the issue persists. There are multiple .mov files in the project I am working on. I have also completely uninstalled and reinstalled After Effects three or four times, removing all plugins.

I would greatly appreciate your help in resolving this issue.
