1,5 hours video corrupt when rendered

Hello guys

I have this problem for a long time and i want to fix this isue. I record my gameplay on my pc and my facecam. Both are seperate files. 

Gameplay is 4K with 59.94 fps and Facecam is recorded also in 4K but 60fps.

When i import the 2 files in Premiere Pro, i make a sequence with the following settings:

3840x2160

59.94 fps

rec 709

quicktime

apple prores 422 lt

Export settings are as follows:

Preset is custom one with 4K 59.94 fps

format is H.264

When Premiere Pro is done with rendering, the file plays as it should be but to a certain point.

If i have a video file of  1h45 min the video plays till 55mins perfect without any issues but then to a certain minute the screen is black and starts playing from the start. 

Is there a fix for this issue?

Thanks
