Export in Media Encoder does not work

Hello folks.
For some time now I have had the problem that I cannot export a composition (around 8 minutes long) and the encoder always says "Failed" and crashes.
I have already made many variations on the resolution, the formats, etc., but I still cannot explain the problem to myself.
The video that I cut is 5GB (1440p resolution, 60fps).
Would anyone have any suggestion to fix this problem to get a good video finally.

I would be very happy about it.
