Encoder not reaction from AE

often encounter the problem that when I want to render from After Effects through Encoder, it doesn’t respond.

•It opens, but the project for rendering doesn’t appear.

•Or you drag and drop the project directly from AE, and it thinks for a while, then doesn’t respond anymore, or the project appears but when I hit render, it keeps thinking and says that such a project does not exist.

•The same thing happens when I import the project directly into Encoder; it might say it can’t find it or, in general, the file I’m pointing to doesn’t load.

I usually noticed that this can happen with large projects, with many compositions, or with effects like Posterize Time.
