After effects stops rendering and freezes at specific point PLEASE HELP

[Lakesha38534866ywoz]

Okay so I was making an edit on after effect but when I went to render it, it freezed at one specific point and it kept doing this. So, I went to that specific point to see if i could pinpoint the problem. I didn't really see any issues so I just assumed it was the motion tile so I removed all the motion tiles in the edit and replaced it with CC Repetile. All the other clips seem to render fine except for this one, I removed all effects all keyframes, but when I do this for some reason it just makes the entire clip blank but it still renders  These are all the keyframes, effects ive used in this clip. Im currently on a macbook pro which is like 2013, and the RAM is 8gb if you need any more information please just let me know I dont know why it keeps freezing at this point

Well, have you actualyl checked the integrity of the source footage? Could simply be a damaged frame. Also flush all disk caches and so on.

Yes i tried that but i already kinda resolved the issue, what i did was just cut out that frame and extended the clip after it to take its place

If you see the issue again, it's best to transcode the source file (as Mylenium pointed out). Videos with variable frame rate (such as screen recordings) can cause issues similar to the ones you're experiencing.

You can also run problem files through the free app Handbrake and make sure the output is a fixed frame rate. This has helped me very much.
