Crashing on export just a few % into process since latest update

So I went to export my dogs birthday video and after just a few % into the export the application either freezes or crashes out repeatedly. I've tried several times with different settings (265 and 264 for example) and it crashes every time.

EDIT: It's happening only when I have BOTH "Remove Grain" and the "Color Plus" checkboxes ticked. I can confirm that the export works with either one option checked or with none checked but not with both checked. It get's stuck at 1.74% in a 1080p H.265 export.

The system is fairly strong with the following specs:

AMD Ryzen 9 3900X

Gigabyte X570 I AORUS Pro WIFI

32GB G.Skill F4-3200 DDR4 RAM

RTX 2080

And it's not a temp related issue as I've been monitoring all temps during the processes and they are all well under anything that should cause trouble.
