Without further study there is no way to say if there is an increased risk of thrombosis from this data alone. Just enough to say they should perform further studies to make a determination. In most cases with these studies, the increased risk of thrombosis would so low that you could offset it by taking a walk once a week.
I personally won't stop my consumption of erythritol on this data alone, but there ARE other sweeteners. I mostly use Stevia myself.
Layne Norton did a quick video explaining the shortcomings of the study.

The problem with studies like this is the reporting on them. I'm fairly sure most people reporting on this study did not actually read it (and you can't read it without paying). And it just plays into the confirmation bias that any non-nutritive sweetener is bad, despite them all being wildly different chemical compounds that all get metabolised in very different ways.
Erythritol has a kinda minty aftertaste.. like on the exhale that can be unpleasant if it's not overpowered by something else.
All that said, I still prefer an erythritol + monkfruit sweetener in beverages. Erythritol is easier on my stomach in larger quantities.
Also, here is a thread from a week ago that also discussed allulose: https://news.ycombinator.com/item?id=34879059
