I’ve seen this issue with SVG’s that I’ve tried to import that have a large number of objects, and it looks like yours is in that same category. you have a massive number of small objects and I dont think that Easel can properly handle this many.
I’d suggest either simplifying the source to have fewer small segments, or copy the project to multiple pages and remove objects until you can get the simulate to run but then you will need to run each page independently.
But honestly looking more closely you really need to remove the ‘noise’ in this work you have multiple redundant paths and small traces that add nothing to the pattern.
Just my $.02
