Premiere Crashes sporadically when using Sequence.exportAsMediaDirect()

Hey, I wrote a CEP Extension that exports the same sequence multiple times in different formats using the Sequence.exportAsMediaDirect() method.

Approximately one in three times Premiere crashes after one of the exports is done (Always random which one). It does this after the "Encoding Sequence"-Window closes and the respective export is done - the output file is also intact. But the next iteration of the loop doesn't start, and if you click anywhere, Premiere is not responding.

This made me suspect some IO issue, but even adding a sleep of 5 seconds between exports doesn't help.

I want to avoid using AME as it handles nested framerates differently, takes time to start up, has to be up to date etc.

How would I debug this? The CEP logs don't show any issues.
