Just replace the BFD3 with a similar Drum Synth.
FWIW: I have found recently that most times it is actually an effect on the "affected" track, these bugging programs give. So, try to bypass the effects bin and do a test export. If it exports without failing, you know its an effect. The job then will be - to replace each effect one-by-one with another giving it the same settings.
If this test still fails, go ahead and replace the entire synth on the channel.
