Shape Map - Incorrectly Displaying
I tried simplifying the shapefile and converting to WGS84 using this command in MapShaper console option.
-proj wgs84

Thank you Danyel! I tried the file you provided and simplified it. Its displaying properly on Power BI now!
I do have a question regarding simplifying, I'm not too familiar with mapping tools like these, on MapShaper for simplifcation, which settings boxes did you tick off for 'Simplification' and 'Method' (Douglas-Peucker, Visvalin Effective Area, Visvalingam Weighted Area, etc) , also how much % did you lower it to for Power BI to process it properly?

I simplified to 20% and it's still quite big. You can probably find a map that's already simplified.
Some of this algorithms can be quite complex, you can read more on wikipedia for example.

I got it down to around 5% and it loaded. Appreciate your help!
