I will probably not help you, but I have similar problem and I also have Unbogus... Freeze (not crash) and music continues playing. I had slightly over 100 hours without any crashes (which I consider a miracle, but I was very conservative in mod choice and I don't have FOSE.). After 1.10 (.20 I think) it started crashing in combat (even outside VATS) and even when I was not in combat, but someone near me was. So Bethesda changed something in creation club update that screwed my setup. I am unable find the culprit, but maybe this is similar to a classical VATS bug, people are complaining about. I gave up on the game for a couple of months, but I would still like to play, especially some story mods. So I am searching forums for the answer and found you problem and I see you have Unbogus, too... so maybe it is in it. But I will not uninstall it since it would make the game uninteresting. ANYWAY, if you come up with a solution or some crazy idea, post it here please. Thanks, I do hope you find a solution.
