Resolve 12 crashes on export

Hello,

I've got an unusual problem.
Resolve 12 crashes on export (no matter which codec and input files) exactly when timeline reaches 18 min 12 sec during exporting. Usually I'm working with Prores files from BM Pocket. I have Zotac PC with Intel i7 4770R, Iris pro 5200, 16 Gb RAM, Win 10 Home. Quite powerful and little box.

My 2nd PC at home exports the same videos without any errors or crashes (i5 3770k, Radeon 7800, Win 10 home).

Has anyone something similar? I have to work soon out of home and continue my project on Zotac.

I would be very grateful for any advise or direction to think.

I just was able to test 12, and had crashes on export. I've not had time to document step by step, but basically I imported some RAW BMPCC footage, did a minor amount of color correction, then attempted to output in ProRes HQ.

I ended up going back to 11.3.1, and export was fine.
