Additional Information I tried with older builds and still encountered the same issue: d75aef40, e9c97407

[Gatewalker-111]

I've had the same issue; crash always seems to happen within 5-6 seconds of beginning the export process.

Already reported at #2211

There, someone mentions checking the source files, and indeed, I swapped the mp4 source file (only had one) and the export worked.
